In 1969, Dilley invited Overlie to make a performance for the Whitney Museum in New York City as a part of her improvisational dance company, Natural History of the American Dancer. Overlie arrived in SoHo in January 1970 while assisting Yvonne Rainer in her research and workshop tour in preparation for Rainer's film Lulu. Overlie continued as a member of the Natural History of the American Dancer with Carmen Beauchat, Cynthia Hedstrom, Judy Padow, Rachel Lew and Suzanne Harris from 1970 to 1975. The company performed at The Whitney Museum, 112 Greene St. Gallery, Ornette Coleman's Artist's House, Paula Cooper Gallery, Bennington College, Oberlin College and other venues. In 1972, Overlie began experimenting with the early explorations of Steve Paxton, founder of Contact Improvisation. From 1975-1979, Overlie danced with the Judy Padow Dance Company before she started her own company and work as a soloist. In 1974, Overlie cofounded Danspace Project, a dance-presenting organization, at St. Mark's Church in-the-Bowery with New York School poet Larry Fagin [9] and choreographer Barbara Dilley. In 1977, Overlie choreographed and performed Window Pieces, Glassed Imaginations and Glassed Imaginations II at the Holly Solomon Gallery, 112 Greene Street, Manhattan.

Mary Overlie 2016 Mary Overlie (January 15, 1946 – June 5, 2020) was an American choreographer, dancer, theater artist, professor, author, and the originator of the Six Viewpoints technique for theater and dance. The Six Viewpoints technique is both a philosophical articulation of postmodern performance and a teaching system addressing directing, choreographing, dancing, acting, improvisation, and performance analysis. The Six Viewpoints has been taught in the core curriculum of the Experimental Theater Wing within Tisch School of the Arts at New York University since its inception (1978). Overlie was the co-founder of several long lasting art institutions such as Danspace Project, the Studies Project, Movement Research, and the Experimental Theater Wing at New York University.

In the Bay Area of California and at Connecticut College, Overlie studied Martha Graham technique with David Wood, Merce Cunningham technique with Margaret Jenkins, and José Limón technique with Anne Swearingen and Betty Jones. Additionally, Overlie studied Transcendental Meditation with Maharishi Mahesh Yogi, becoming a Transcendental Meditation teacher in 1968. The teachings of Transcendental Meditation would later influence the philosophical foundations of the Six Viewpoints, specifically as a process of refinement for conscious awareness During her years in San Francisco, Overlie danced with the Anne Swearingen Dance Company, the Teresa Dickensen Dance Company, the San Francisco Mime Troupe, and the Jan Lapiner Dance Company. She later performed in works choreographed by Yvonne Rainer and Barbara Dilley, founders of the Grand Union.

Sandy beach ridges (marking the western shore of Lake Agassiz at various times) lie throughout the area: a prominent beach ridge lies under the town's golf course, just west of town. Valley soils are typically very fertile and deep, and are the area's greatest natural resource. But they also have a high calcium carbonate content and an alkaline pH, which limits their productivity in some crops (for example, blueberries). The underlying bedrock is composed of Cretaceous shales, and, below that, sandstone, which overlie deeper deposits of Devonian limestone, which in turn overlie Precambrian granite.

The pieces were performed in the storefront windows of the gallery to audiences on the sidewalk of New York's SoHo neighborhood. Ron Argelander invited her to join him as the first teacher of the Experimental Theater Wing of Tisch School of the Arts at New York University. Sylvère Lotringer interviewed Overlie for Semiotext(e) edition Notes on the Schizo-Culture Issue (1979) alongside Jack Smith, Philip Glass, Michel Foucault, Gilles Deleuze, Robert Wilson, John Cage and other leading philosophers and artists "that had already devoted their thought to the perpetual collapsing of borders." This interview posited Overlie as notable exponent of post-modernism.

At many localities along the sea cliffs, typically over 10 meters of Early Weichselian lacustrine and loess-like floodplain deposits overlie the Eemian and pre-Eemian sediments. These sediments consist of fine-grained, well-sorted sands with rare grass and sedge pollen. They contain ice wedge polygon systems that formed during the Early Weichselian stadial, about 100,000 to 50,000 years ago, as the result of extremely cold and dry conditions. Typically, 15 to 20 meters of Middle Weichselian ice complex deposits, which consist largely of aeolian sediments that accumulated 50,000 to 28,000 years ago, overlie the Early Weichselian sediments.

Abstract This deformed zone gives the best estimate for the original size of the crater. Impact took place after folding of the Paleoproterozoic rocks but before deposition of Neoproterozoic and Cambrian rocks which overlie them, thus constraining the impact event to the interval between about 1660 and 600 Ma.

The act of deconstructing performance into its six materials invites the performer, director, artist to engage with the individual materials "allowing these elements to take the lead in a creative dialogue". For Overlie, this shift in attention re-defines art and the role of the artist from a "creator/originator" mindset to what she called the "observer/participant," which centers on "witnessing, and interacting, ... working under the supposition that structure could be discerned rather than imposed". Overlie observed this redefinition of the artist's endeavor to correspond with the artistic shift from modernism to post-modernism. The theory and practice of the six viewpoints is organized in two parts: The Materials and The Bridge.

Bauxites of the Mediterranean province generally overlie the karstic surfaces of limestones or dolomites. The deposits form pockets, lenses, chains of pockets or lenses, and sometimes extended sheets. The bauxite sheets tend to slope, either gently or steeply; only on the Hungarian Massif do the sheets lie almost horizontally. The sheets that are currently being mined range in thickness from 1 m to 8 m.

The Lower Jurassic rocks conformably overlie the Upper Triassic units; so are the Early Cretaceous deposits over the Upper Jurassic strata (e.g., Zagros). In North and Central Iran, the Upper Triassic and Lower–Middle Jurassic sediments have a detrital nature, consisting mainly of shale and sandstone with thicknesses varying from a few meters to more than . The presence of plant remains and coal beds suggest a continental or lagoon environment for the deposits.

The soils are shallow and often overlie extensive sheets of laterite (ironstone) and a thick profile of strongly leached rocks. Mamukala During the wet season water carried down from the Arnhem Land plateau often overflows from creeks and rivers onto nearby floodplains. Alluvial soils carried in the floodwaters add nutrients to the floodplains. Nutrient-rich soils along with an abundance of water and sunlight make the floodplains an area of prolific plant and animal life.

The surface expression of Kelly West comprises a circular hill of Palaeoproterozoic quartzite about in diameter, interpreted as a central uplift of a larger complex impact crater. Recent geophysical interpretation suggests an original crater diameter of , less than earlier estimates of about . The age is poorly constrained, but must be older than Middle Cambrian because sedimentary rocks of this age overlie the central uplift and were not deformed by the impact event.

The Thermopolis Shale belongs to both the Colorado Group and Dakota Formation. Both historically and currently, the stratigraphic units in these groups, and in the Thermopolis Shale, have been unclear, and the nomenclature used by geologists is not standardized. The identification of beds, members, and formations and their names have changed over time as well. The Thermopolis Shale is said by Eicher to overlie the Cloverly Formation, although Rice, Porter et al.

The higher ground of the fell is composed of flows of andesite lava, belonging to the Birker Fell Andesite Formation, a part of the Borrowdale Volcanic Group. These rocks are part of a thick succession of lava sheets found around the western and northern sides of the Lake District. They were formed by eruptions of mobile lava from shallow-sided volcanoes. They are a little younger than the Skiddaw mudstones, which they overlie.

The coal bed belongs to either or Cheuquemó Formation or Estratos de Pupunahue. ENAP geologists have instead named "Osorno Formation" the coal- bearing formation and estimated a Serravallian age for the marine strata that overlie the coal beds. Mining is facilitated by the lack of any significant fault displacement of the coal beds. The coal of Catamutún are sub-bituminous, low in sulfur and of heat contents of 5,800–6,150 Kcal/kg.

The plate-like formations found on the shells of turtle and tortoise shells are called "scutes." These scutes are large, protective epidermal cells that overlie the interlocking bones beneath the shell's carapace, or upper shell. Scutes are made of keratin, a protein which also makes up human fingernails, along with the horns and claws of some animals. There are different titles for scutes, depending on what region of the shell they occupy.

The plateau regions have high elevations ranging from . Extensive horizontal mesas are capped by sedimentary formations and support woodlands of junipers, pinon, and ponderosa pines, each favoring different elevations. Wind and water erosion have created steep-walled canyons, and sculpted windows and bridges out of the sandstone landscape. In areas where resistant strata (sedimentary rock layers), such as sandstone or limestone, overlie more easily eroded strata such as shale, rock overhangs formed.

Deposition within the basin occurred fast enough to fill it with up to seven kilometers of sedimentary rock in only five million years. While most of the rocks filling the basin are marine sediments, some igneous rocks from the Conejo Volcanics series overlie them.Richards, 1-3 Oil accumulations, which are common in the Ventura Basin, mainly occur in anticlinal settings modified by faulting. Stratigraphy is also influential in creating traps for hydrocarbons.

The still unnamed Cardenas Basalt is only briefly noted as exposures of it are absent in the Shinumo 15-minute quadrangle. Although a recognized part of the Unkar Group, the basalt lava flows that overlie the Dox Formation were generally ignored and simply described as "basalt and diabase." In 1938, Charles R. Keyes applied the name "Cardenesan Series" to the basaltic volcanic rocks within the Unkar Group.Keyes, C (1938) Basement complex of the Grand Canyon: Pan American Geologist.

When lava flows were erupted from Tuber Hill, they interacted with the valley-filling glaciers on its southern flank and produced a glacial meltwater lake. Here, more than of stacked hyaloclastite, lahars and lacustrine tuff were deposited. A series of pillow lavas were also deposited during this eruptive period. The most recent volcanic activity in the Bridge River volcanic field produced a series of basaltic lava flows in the regional valleys that overlie till of the last glacial period.

Ingatestone lies just to the north of the southernmost limit of glaciation in the British Isles. Surface deposits over much of the area consist of boulder clay and it is only to the north-east that there are more sandy deposits. Geologist Ciara Lovatt conducted several rock mineral experiments on deposits within Ingatestone in the 1980s. The glacial deposits overlie London clay, which can be seen occasionally in the bed of the River Wid and its tributaries.

Mineable coal seams have been used since the mid-late 16th century. The Coal Measures in the area overlie the Millstone Grit which has been quarried in the past for millstones and, along with local limestone deposits, used as a construction material for roads and buildings. Blackburn was bisected by the Leeds and Liverpool Canal which provided a transport facility for the earlier mills, but by the time that Imperial Mill was built this was less important.

Together with mafic rocks and andesite, they are evidence of back arc environment. The late Neoproterozoic Belle-Riviere Group includes bimodal volcanic rocks such as basalt and rhyolite overlain by terrestrial sedimentary rock. Belle-Riviere Group rocks partially overlie the Tommotian Fortune Group and the early and middle Cambrian Langlade Group, which have fossiliferous limestone beds and siltstone. Discordant contact between older Precambrian rocks and Paleozoic sedimentary rocks as well as thrust faults indicate Acadian orogeny related deformation.

The railroad installed a roundhouse for servicing locomotives as well as coal and water facilities. A popular pastime for city residents was to gather at the rail depot on the edge of town to watch the trains in the mornings and evenings. Many speculate that the town's name was meant to describe the numerous rail crews that "laid over" in town during the shift changes. Others say the town is named for Hans Overlie, an early settler.

Foinaven () is a mountain in Scotland, situated in the far north-west corner of the Scottish Highlands. Like many of the monolithic mountains that surround it, the mountain is within the Moine Thrust Belt and is made up of imbricated layers of Cambrian quartzite which overlie the older Lewisian gneiss basement. The quartzite, being tougher, stood firm when all the surrounding rock was eroded away, leaving the huge mountain isolated. Its highest point is named Ganu Mòr.

Because overbank deposits often overlie areas that are normally exposed to weathering, they can bury soils, allowing those soils to be preserved as paleosols. Paleosols can serve as bounds for overbank depositional sequences or alternate with overbank deposits where flooding is episodic. Paleosols tend to show more maturity at a greater distance from the channel, where there is less sediment flux. The degree of soil horizon development can be used as a proxy for this process.

This collision deformed strata within the ridge in a northward plunging series of asymmetric folds (e.g., anticlines and synclines) that are inclined gently westward. These same folds, involving strata that overlie the Shawangunk Conglomerate, are exposed north of Shawangunk Ridge in the Rosendale Natural Cement Region, where they can be directly examined in abandoned mines. Strata along the eastern margin of Shawangunk Ridge are truncated by erosion, resulting in the prominent cliffs characteristic of Shawangunk Ridge.

These deeply weathered sediments are unfossiliferous and characterized by the presence of weathering products like kaolinite and montmorillonite. Saalian sediments uncomfortably overlie this paleosol. The oldest known Pleistocene sediments exposed in the southern sea cliffs of Bolshoy Lyakhovsky Island consist of Saalian sediments, which accumulated between 200,000 and 120,000 years ago. The lower part of these sediments consist of ice-rich, silty and silty-sandy sediments that accumulated as a Saalian ice complex between 200,000 and 170,000 years ago.

The highest point of the volcano lies east-northeast of the caldera and reaches elevation. The caldera has an incomplete rim and is filled with snow, leaving a depression. The rim of the caldera is covered by volcanic ejecta including lapilli and lava bombs, probably the products of the most recent eruption of Mount Melbourne, which overlie a layer of pumice lapilli. Three small, nested craters formed by phreatomagmatic eruptions occur on the southern rim of the summit caldera.

The town is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age. The soil in area is a mixture of well-draining material, loess, and loam, which all overlie a layer of glacial till. The town has some Silurian limestone deposits, including land around the City of Cedarburg. The early settlers utilized the area's limestone as a building material, and some mid-19th-century limestone structures still stand today.

The soil in area is a mixture of well-draining material, loess, and loam, which all overlie a layer of glacial till. Most of the City of Cedarburg is located on top of a Silurian limestone deposit. There were several quarries active in the area, including the now-defunct Groth Quarry in Zeunert Park where excavators discovered fossils from a prehistoric reef. The early settlers utilized the area's limestone as a building material, and some mid-19th- century limestone structures still stand today.

The soils here are shallow, sandy and low in nutrients and overlie heavy clay. Drainage is therefore slow, the water table is consistently close to the surface, and marshes and bogs are common. These wetter areas are known as wallum, and are dominated by open sedgeland and Banksia heathland, which grade into patchy forests and woodland on the upper dune slopes and crests. Common forest and woodland trees are White Mahogany (Eucalyptus umbra), Pinkwood (Eucalyptus internmedia) and Broad leaved Paper-bark (Melaleuca quinquenervia).

The observatory and its grounds are located within the grounds of the Royal Mid-Surrey Golf Club, which is part of the Old Deer Park of the former Richmond Palace in Richmond, historically in Surrey and now in the London Borough of Richmond upon Thames. The former royal manor of Kew lies to the immediate north. The observatory grounds overlie to the south the site of the former Sheen Priory, the Carthusian monastery established by King Henry V in 1414.Diagram on p.

Rocks in Glacier Bay and the Heceta-Tuxekan Islands to the west of Prince of Wales Island preserve clam shells and reef life. In many locations, Alexander terrane limestone rests on top of conglomerate made up of beach boulders. Volcanic rocks, carbonates and phyllite overlie these lower rock units, intruded by Jurassic igneous rocks. Many sections of the terrane are highly metamorphosed and broken into smaller blocks by faults, such as the Chatham Strait Fault, which offsets rocks up to 120 miles.

Zidini Formation interglacial lakebed sediments overlie the Latgale up to 23.5 meters thick. The overlying Letiza Formation correlates with formations such as the Oka in Russia or Sangaste in Estonia, associated with the Elsterian glaciation and includes till atop Jurassic rock. Eight meters of lacustrine sediment in the Pulvernieki or marine clays in the Akmenrags Formation line up with the mid-Pleistocene Holsteinian glaciation. Along the Baltic coast, up to 60 meters of brackish sand—the Jurkalne Member—overlies the Akmenrags Formation.

The Bonchurch Landslip (also called East End Landslip) involves a coastal Cretaceous sequence where harder Upper Greensand rocks overlie softer Gault clay. It has SSSI status for its geomorphological interest (the Undercliff itself, and the landslips and mud flows below) and its botanical assemblage. The Gault clay supports established woodland of ash, oak and beech, with unusual lichen species. The lower slips, comprising mixed clay and sandy habitats, support a complex mix of acid-loving and chalk-loving plant species.

Harden is a small lunar impact crater that lies in the eastern part of the interior floor of the walled plain Mendeleev. It is located on the far side of the Moon, and cannot been seen from the Earth. The crater is a circular, bowl-shaped feature with a slightly higher albedo than the surrounding terrain, but lacks the skirt of bright ejecta that many young impacts possess. The edge and interior are not notably eroded, and no significant craters overlie this feature.

Carboniferous and Permian turbidite sequences overlie these groups in south, west and central Thailand. Thick sequences of clastic sediment in the Kaeng Krachan Formation extends from the center-west into Myanmar. Some geologists have interpreted pebbly diamictite mudstone and turbidites in the Mergui Group as glacial sediments, with possible origin in India or northwest Australia. One interpretation holds that the Mergui Group was thrust on top of the Shan-Thai Block from the west during the Mesozoic, forming a nappe.

Gilwern Hill is formed from a series of rock strata of Carboniferous age, each of which dip moderately southwards. The summit plateau is formed from sandstones - the Farewell Rock and the Twrch Sandstone which overlie the Carboniferous Limestone. The latter has been extensively quarried around the eastern, northern and western margins of the hill where it is exposed. Derelict tramways are in evidence in connection with the working of these quarries for limestone in connection with iron and steel-smelting.

Its maximum latitude and elevation is thought to be increasing due to climate change. This shrub grows on low-nutrient soils in cold regions, often soils that overlie permafrost. It is most common in moist areas, such as the shores of lakes and bays, riverbanks, bogs, and wet forest floors. It is often a pioneer species in the primary phase of ecological succession, taking hold in areas cleared of vegetation such as floodplains, bare tundra, cleared spots on taiga, and newly formed dunes.

He separated these layers into 6 different spectra, labeled zones U through Z. The law of superposition is important to note when discussing sedimentary layers; this law states that more recent layers of soil dispersal will overlie older ones. Zone U The bottom of Clark's core sample is the oldest layer. Pollen samples collected indicate that swamp vegetation and an abundance of grass grew on the Kalambo River. The tests also indicated that the surrounding woodland grew during dry and hot climates.

The sandstones, siltstones, mudstones and coals of the Pennine Coal Measures Group overlie the Stainmore Formation and, from a line roughly between Amble and Derwent Reservoir via Morpeth, Ponteland and Stocksfield, extend eastwards to the coast with a gentle regional dip towards the North Sea basin. The upper Coal Measures are absent from Northumberland. Further small outliers of the lower Coal Measures extend westwards to the Cumbrian border southwest of Haltwhistle. The Northumberland Coalfield is contiguous with the Durham Coalfield to its south.

Tarjadia has been diagnosed on the basis of its osteoderms, or bony scutes, the most common material that has been found of the genus. The paramedian osteoderms, which overlie the back to either side of the midline, are thick and rectangular. Their medial edges are serrated, allowing the two rows to suture tightly together. Smaller, more rounded osteoderms are thought to have been placed to the sides of the paramedians, although no articulated remains bearing these lateral osteoderms have been found to prove this.

Geologists debate the exact origins of the island and some have proposed that Ascension Island may overlie a diverted shallow mantle plume. Alternately, the island may have originated from anomalously enriched magma, originally at the Mid-Atlantic Ridge, but now situated to the west of it. The petrology of Ascension is unusual. Compared to most other volcanic islands, which only have a few mafic and felsic endmembers such as basalt or rhyolite, Ascension has a full-range from some of the most mafic to most felsic.

Terminology in archaeology is not definitive but the following are typical uses of terms: # Cuts: A context is said to cut another context if the former's creation removed a part of the latter. For example a ditch cut, cuts all the contexts that made up the ground the ditch was dug into. Reciprocally, a context may be said to be cut by another. # Overlies: A context is said to overlie another when the overlying context is later in time and makes physical contact with the earlier context.

Finally, during the Miocene- Quaternary the Sencca Formation and the "Barroso" volcanics developed; Chachani is classified as part of the Barroso volcanics although the oldest volcanism might belong to the "Sillapaca" unit. The terrain of the volcano is formed by volcanic rocks of Eocene to recent age, which overlie a Precambrian basement and include widespread Neogene-Quaternary ignimbrites. Chachani straddles the margin between the higher-elevation Altiplano and the Arequipa basin at lower altitude. The younger El Misti volcano lies southeast of Chachani, across the Rio Chili.

The unconsolidated sediments that overlie the bedrock are exposed in some of the cliffs along the upper edges of the valley. They may include glacial till at the base, overlain by post-glacial stream deposits, loess, and paleosols, and are topped by recent soil horizons. The Mazama Ash, a layer of white volcanic ash a few centimetres thick, can be seen within these sediments in a few places. The Mazama Ash was produced during the eruption that formed Crater Lake in south-central Oregon.

The Guijarral Hills are a range of low hills in the inner California Coast Ranges, in Fresno County, California, about seven miles east of the town of Coalinga. Guijarral is derived from a Spanish word meaning "heap of pebbles". They are the surface expression of an anticlinal structure which continues to the south as the Kettleman Hills, and to the north as Anticline Ridge, a portion of the huge Coalinga Oil Field. The Guijarral Hills overlie the smaller and mostly exhausted Guijarral Hills Oil Field.

A white marking, such as the large snip on this horse's muzzle, usually has pink skin underneath it, except on the edges. White markings are present at birth and unique to each horse, making them useful in identifying individual animals. Markings usually have pink skin underneath them, though some faint markings may not, and white hairs may extend past the area of underlying pink skin. Though markings that overlie dark skin may appear to change, the underlying skin color and hair growing from pink skin will not.

The epidermis is the outermost of the three layers that make up the skin, the inner layers being the dermis and hypodermis. The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss. The epidermis is composed of multiple layers of flattened cells that overlie a base layer (stratum basale) composed of columnar cells arranged perpendicularly. The rows of cells develop from stem cells in the basal layer.

The Tibetan-Tethys Himalayas generally begins from the top of the Higher Himalayan Zone and extends to the north in Tibet. In Nepal these fossiliferous rocks are well developed in Thak Khola (Mustang), Manang and Dolpa area. This zone is about 40 km wide and composed of fossiliferous sedimentary rocks such as shale, sandstone and limestone etc. The area north of the Annapurna and Manaslu ranges in central Nepal consists of metasediments that overlie the Higher Himalayan zone along the South Tibetan Detachment system.

Because of the danger of natural disasters, much of the church's aesthetic had to be sacrificed in favor of durability and functionality. The interior of the church featured artwork dating back to the 19th century, with trompe l’oeil paintings by Italian painters Alberoni and Dibella, but they overlie the original tempera murals. The church was richly endowed, with a fine retablo, pulpit, lectern and choir-stalls. The church also includes oriental details in the form of Chinese fu dogs that flank the entrance of the building.

The river rises in the Dorset Downs at Evershot, passes through Maiden Newton, Dorchester, West Stafford and Woodsford. At Wareham it and the River Piddle, also known as the River Trent, flow into Poole Harbour via the Wareham Channel. The catchment area is ,map approximately one sixth of the county. East of Dorchester the river runs over sands, clays and gravels which overlie the chalk; as the valley gradient is gentle the Frome has deposited much sediment here and thus created a broad flood plain.

Sriperumbudur belongs to the Sriperumbudur Formation, which is characterised by arenaceous and argillaceous rock units composed of splintery green shale, clays, and sandstones with ironstone intercalation. The rock units conformably"(of rock strata) lying in a parallel arrangement so that their original relative positions have remained undisturbed" overlie either the Precambrian basement or Precambrian boulder beds and green shales. The beds contain marine intercalations. Their lithologic suites and fossil fauna are suggestive of deposition under shallow and brackish conditions, probably close to the shoreline.

These groups appear to have formed simultaneously, as no specific stratigraphic sequence is evident. On the basis of crater clusters of similar appearance in the lunar highlands, which have been interpreted as Imbrium and Orientale basin secondaries (Schultz, 1976; Wilhelms, 1976b; Eggleton, 1981), these crater groups are interpreted to be Caloris Basin secondaries. Following the terminology developed by McCauley and others (1981) we have assigned them to the Van Eyck Formation, Secondary-Crater Facies. These secondaries overlie Dostoevskij ejecta and thus confirm that basin as pre-Caloris.

Word generation tasks including rhyme generation (phonological bases), synonym generation (semantic search bases), and translation (lexical access to other language) are used to observe lexical-semantics. Word generation has been shown to cause significant activation in the left dorsolateral frontal cortex (Brodmann areas 9, 45, 46, 47). Considerable overlie has been found in the frontal areas, regardless of task requirements (rhymes or synonyms) and language used (L1 or L2). Selective activation is observed in the left putamen when words are generated in the second language (i.e.

Dar-Alages () is a group of six cinder lava cones south of Lake Sevan in Armenia. Fissure eruptions from Vaiyots-Sar dammed the Arpa river at Vayk and continued down the valley for 6 km. These lava flows are considered Holocene in age given the lack of a soil cover and their placement above a Pleistocene river terrace. Smbatassar cinder cones likewise generated two lava flows of 11 and 17 km length that overlie Pleistocene Yeheghis river terraces, thus also dating to the Holocene.

Sandstones, which are sometimes graded, overlie each of these beds. The basal few centimeters of the muddy sandstones frequently consist of a contorted mud-flake breccia derived from the underlying siltstone and is contorted by load structures. Silicified peat, silicified logs, and fossil leaf compressions and impressions have been found in the Buckley Formation at Turbidite Hill and Mount Cerberus and in the Geologists Range and Black Nunataks. The fossil peats and logs may be the oldest silicified Permian plant material that has been found in the central Transantarctic Mountains.

The Neoproterozoic Nankoweap Formation (pronounced Nan' coe weep), is a thin sequence of distinctive red beds that consist of reddish brown and tan sandstones and subordinate siltstones and mudrocks that unconformably overlie basaltic lava flows of the Cardenas Basalt of the Unkar Group and underlie the sedimentary strata of the Galeros Formation of the Chuar Group. The Nankoweap Formation is slightly more than 100 m in thickness. It is informally subdivided into informal lower and upper members that are separated and enclosed by unconformities. Its lower (ferruginous) member is 0 to 15 m thick.

They overlie firm alluvial soils which contain two sand layers at 92 and 110 feet (29 and 35 meters), respectively. This section, in turn, overlies shale of the Franciscan Complex, a heterogeneous mixture of sedimentary, igneous and metamorphic rock gathered together in the course of the tectonic evolution of the region from the Late Jurassic to the Middle Miocene. These assemblages of Franciscan rocks are referred to as tectonostratigraphic terrains and two of them, the Central Belt and the Coastal Belt, are in fault contact near Richardson Bay.

These strata unconformably overlie Archean strata of the Superior craton and Proterozoic Richmond Group. The unconformity between the Early Proterozoic Nastapoka Group and the underlying Archean Superior craton lies just inland of Nastapoka arc as defined by the edge of arcuate eastern coastline of Hudson Bay. The unconformity consists of undeformed stromatolite-bearing dolomites overlying either foliated Archean granodiorite or the tilted and eroded strata of the Richmond Gulf Group. A thin, conglomeratic quartz sandstone separates the dolomites from the underlying strata and forms the base of the Nastapoka Group.

Major lava flows have formed vast plateaus that overlie Paleozoic sandstone. The volcanic activity was the result of a continental hotspot that arose during the Oligocene and continued in some places until the Holocene, creating fumaroles, hot springs, mud pools and deposits of natron and sulfur. Erosion has shaped volcanic spires and carved an extensive network of canyons through which run rivers subject to highly irregular flows that are rapidly lost to the desert sands. Tibesti, which means "place where the mountain people live," is the domain of the Toubou people.

Red dots show breeding colonies in the north Atlantic The northern gannet's breeding range is on both sides of the North Atlantic on coasts influenced by the Gulf Stream, There are colonies in the Gulf of Saint Lawrence and on the islands off the east coast of Canada. They normally nest in large colonies, on cliffs overlooking the ocean or on small rocky islands. The water needs to be cool enough for Atlantic mackerel and herring, which are the main food source for the northern gannet. These areas also overlie the continental shelf.

Viewpoints is a technique of dance composition that acts as a medium for thinking about and acting upon movement, gesture and creative space. Originally developed in the 1970s by master theater artist and educator Mary Overlie, the Six Viewpoints has been studied and practiced for decades in theatre and dance. Overlie's practice and theory profoundly enables access to the source of inspiration and creativity. The Six Viewpoints, if practiced in the purest form, is found to be indescribably powerful and effective in all areas of investigation of, and for making art.

Chappell is a lunar impact crater that is located on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. This feature is located in a heavily bombarded section of the surface, and much of the outer rim of the crater is overlain by many smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.

Slopes evolve by parallel retreat when rock strength remains constant and basal debris, like talus, is continuously removed. These conditions are often met in areas where hard horizontal rock layers of basalt or hard sedimentary rock overlie softer rocks. Slopes tend to cease to evolve by parallel retreat once overlying hard layers covering softer rock have been fully eroded. As rock strength is related to weathering and weathering to climate in the case a slope retreat over large distances or over long time- spans retreat is unlikely to remain fully parallel.

It consists of nine volcanic cones that overlie a sedimentary structural high; the cones and the structural high make up the seamount. The wide 'Vince volcano' is the largest volcanic cone and forms a solitary northeasterly summit; the other eight are clustered in the southwest and one of these forms the shallowest point of the seamount. The southern slopes are steep and feature canyon-like features, the northern slopes are more gentle. Two faults, the North Coral Patch Ridge fault and the South Coral Patch Ridge fault, run northeastward away from Coral Patch Seamount.

The remains of a Mesolithic elk found caught in a bog at Poulton-le-Fylde in Lancashire show that it had been wounded by hunters and escaped on three occasions, indicating hunting during the Mesolithic. A few Neolithic monuments overlie Mesolithic sites but little continuity can be demonstrated. Farming of crops and domestic animals was adopted in Britain around 4500 BC, at least partly because of the need for reliable food sources. The climate had been warming since the later Mesolithic and continued to improve, replacing the earlier pine forests with woodland.

A series of pillow lavas were also deposited during this eruptive period. The most recent volcanic activity in the Bridge River volcanic field produced a series of basaltic lava flows in the regional valleys that overlie till of the last glacial period. The age of these valley-filling lava flows is unknown but the presence of unconsolidated glacial till under the flows suggests that they are less than 1,500 years old. To the northwest, the Franklin Glacier Complex is a set of volcanic bedrock that encompasses an area long and wide.

The geology is complicated due to folding, faulting and thrusting and are largely unfossiliferous. Tectonically, the entire Lesser Himalayas consists of two sequences of rocks: allochthonous, and autochthonous-paraautochthonous units; with various nappes, klippes and tectonic windows. The northernmost boundary of the Siwaliks Group is marked by the Main Boundary Thrust (MBT), over which the low-grade metasedimentary rocks of the Lesser Himalaya overlie. The Lesser Himalaya, also called the Lower Himalaya, or the Midlands, is a thick (about 7 km) section of para- autochthonous crystalline rocks made up of low- to medium grade rocks.

Rocks left over from the Turkestan Ocean crust form allochthon units on the northern edge of the Karakum-Tajik microcontinent. In the western part of the Turkestan structure, in the Kyzylkum Desert, andesite lava flows and tuff overlie Ordovician-Silurian carbonate and pelite. Nappe formations, such as the Kulkuduk Unit are composed of basal serptinized dunite and lherzolite, with overlying harzburgite and layered gabbro. These are cut by granite dikes and intrusions and are overlain by tube basalt, pillow basalt and sedimentary rocks such as ophiolite breccia, green and red pelagic shales, limestone and olistoliths.

They exhibit mantle bedding—the deposits directly overlie pre-existing topography and maintain a uniform thickness over relatively short distances. Sorting by size is more pronounced than pyroclastic surge or pyroclastic flows. Early settling of crystals and lithic fragments near an eruptive vent and of glassy fragments further away is a common trend witnessed during many eruptions. The St Vincent eruption in 1902 ejected a large eruption column which when settled near the vent contained 73% crystals, and ash deposited in Jamaica 1,600 km away consisted entirely of glass dust.

The Hindsville Formation, or Hindsville Limestone Member of the Batesville Formation, is a geologic unit in northern Arkansas and eastern Oklahoma that dates to the Chesterian Series of the late Mississippian. Named for the town of Hindsville in Madison County, Arkansas, this unit is recognized as a member of the Batesville Formation in Arkansas and a geologic formation in Oklahoma. Although, some workers have proposed raising the rank of this interval in Arkansas to formation status. Both the Batesville and Hindsville Formations overlie the Moorefield Formation and underlie the Fayetteville Shale.

Chinese oil reserves China's onshore oil resources are mostly located in the Northeast and in Xinjiang, Gansu, Qinghai, Sichuan, Shandong, and Henan provinces. Oil shale is found in a number of places, especially at Fushun in Liaoning, where the deposits overlie the coal reserves, as well as in Guangdong. High quality light oil has been found in the Pearl River estuary of the South China Sea, the Qaidam Basin in Qinghai, and the Tarim Basin in Xinjiang. The country consumes most of its oil output but does export some crude oil and oil products.

The Paleozoic rocks broke off at the level of the Lancara Formation and were thrust over the top the upper layers forming nappes and thrust sheets. The Ponga Nappe Province is to the east of the Central Coal Basin, Stephanian age molasse deposits overlie the other Carboniferous rocks and are unrelated to the Hercynian (Variscan) orogeny. Some final folding occurred at right angles to the Westphalian structures. Further uplift occurred, and in the Stephanian period there were some land locked basins in the mountains over the west and south nappes.

While multicuspid teeth are seen in many other notosuchians such as Simosuchus and Yacarerani, they are most complex in Pakasuchus. The molar-like teeth show a level of complexity that matches that of mammals, being able to occlude, or fit with one another, and provide sharp shearing edges for slicing food. Pakasuchus also differed from modern crocodilians, and many other crocodyliforms, in the reduction of osteoderms covering the body. Small, reduced osteoderms overlie the dorsal vertebrae, but fewer in number and are not as large as those of other notosuchians.

The San Ardo Oil Field is the farthest north of the major oil fields west of the San Andreas Fault in California; most of the other large fields are east of the fault. As is common with California oil fields, the San Ardo Field is an anticlinal structure. The productive units are the Aurignac Sands, which are a portion of the huge Monterey Formation, a sedimentary rock unit which underlies much of coastal California. These sands are an average of about thick, contain an abundance of heavy crude oil, and overlie granodioritic basement rocks.

Recently, Abrams expanded upon the synthesis of CBT and evolutionary psychology with the book The New CBT: Clinical Evolutionary Psychology. This book which set forth a new variation of CBT called informed cognitive therapy (ICT) took what was implied in much of Ellis' work and made it explicit. Abrams combined evidence from behavioral genetics and evolutionary psychology to add to the effectiveness of CBT in a clinical text proposing a new variant of CBT. Abrams argues that most psychological disorders overlie a latent factor common to virtually all pathologies.

Major gyri and sulci on the lateral surface of the cortex Lobes of the brain The cerebrum is the largest part of the brain, and is divided into nearly symmetrical left and right hemispheres by a deep groove, the longitudinal fissure. Asymmetry between the lobes is noted as a petalia. The hemispheres are connected by five commissures that span the longitudinal fissure, the largest of these is the corpus callosum. Each hemisphere is conventionally divided into four main lobes; the frontal lobe, parietal lobe, temporal lobe, and occipital lobe, named according to the skull bones that overlie them.

The Kettleman North Dome occupies the northernmost portion of the Kettleman Hills, a northwest-southeast trending line of hills about long which parallels the San Andreas Fault to the west. The range consists of two elongate "domes", the North Dome and Middle Dome; a portion of the Middle Dome is sometimes called the "South Dome," although the North and Middle Dome are the most topographically distinct. Both the North and Middle Domes overlie oil fields. The Kettleman Hills is named, and misspelled, after Dave Kettelman, a pioneer sheep and cattle rancher who grazed his animals there in the 1860s.

The tenement straddles the southern boundary of the Mara-Musoma greenstone belt with granites but the geology is largely covered by thin soils overlying sub-cropping residual laterites. The greenstones are most likely part of the Nyanzian System and the southern portion of the tenement is covered extensively by mbugu soils which are interpreted to overlie granite. At least 4 km of ESE striking granite- greenstone contact has been identified from reconnaissance mapping. Structural interpretation of the magnetic and gravity geophysical data indicates a series of easterly trending structures parallel the main contact into the greenstone sequences.

Palatinate Forest (Pfälzerwald) with Upper (left) and Lower (right) Mundat Forests (ochre tint) at the southern border The term 'Mundat Forest' refers to two forests that overlie the modern border between Germany and France near Wissembourg, Alsace. The Upper Mundat Forest is a small part of the mountainous Palatinate Forest. The smaller Lower Mundat Forest forms a fraction of the Bienwald in the Upper Rhine valley. In the Middle Ages the forests were part of the Wissembourg Mundat, the privileged possessions of the abbey of Weissenburg (now Wissembourg), whose abbot was a territorial magnate, a Prince-abbot of the Holy Roman Empire.

Early-Mid Jurassic (170 Ma) On Bornholm, the lower-middle Jurassic succession is composed of the Rønne (Hettangian-Sinemurian), Hasle (Lower-late Pliensbachian), Sorthat and Bagå Formations. The major Pliensbachian–Bathonian coal-bearing Clays and Sands that overlie the Lower Pliensbachian Hasle Formation are distributed between the to the new Sorthat Formation and the Bagå Formation. The Sorthat Formation is the regional equivalent of the Ciechocinek Formation on Baltic Germany and Poland, the Fjerritslev Formation on the Danish Basin, the Rya Formation on Scania. The Sorthat Formation beds where referred originally to the Levka Beds, Sorthat and Bagå beds.

There were decades of minor earthquakes, more than at any other time in the historical record for Northern California, before the 1906 San Francisco earthquake. Previously interpreted as precursory activity to the 1906 earthquake, they have been found to have a strong seasonal pattern and due to large seasonal sediment loads in coastal bays that overlie faults as a result of mining of gold inland.Seasonal Seismicity of Northern California Before the Great 1906 Earthquake, (Journal) Pure and Applied Geophysics, ISSN 0033-4553 (Print) 1420-9136 (Online), volume 159, Numbers 1–3 / January, 2002, Pages 7–62.

In recounting the building practices of the local area, Astbury notes that major structures such as the monasteries at Ely, Thorney and Crowland were built on islands or ridges. These structures rest on Cretaceous Lower Greensand that overlie Jurassic period Kimmeridge on top of Jurassic period Ampthill clays. For example, the village of Little Thetford, south of Ely, lies at about above sea-level, and sits largely on an island of Kimmeridge Clay, a Jurassic shallow-water shelf-sea deposit. Underlying the Kimmeridge Clay are older Jurassic clays, which also contain thin beds of limestone and sandstone.

In December 1984, Langland choreographed and performed Circa 1950–51, along choreographer Le Schaetzel at Bessie Schönberg Theatre. In October 1989, Langland performed in the same theatre's Nuts (Homage to Freud). In 1990, Langland perform in Sharon Wyrrick's Full Circle Company at the Kennedy Center Terrace Theater. Langland has also performed with Steve Paxton, Mary Overlie, Barbara Dilley, Ping Chong, David Gordon, Simone Forti, Andrea Klein and Channel Z. His many choreographic works include "Almost Rapture" co-choreographed with Brendan McCall, which was a North America Division Finalist for Choreography in the 1998 Sixth Recontres Internationales Choreographique de Seine-Saint-Denis.

Dark red Triassic shale and wind-blown sands transformed into sandstone overlie Permian rocks, marking the beginning of the Mesozoic. The sea reached western Colorado and the area was blanketed in ash fall from eruptions to the west. Early Jurassic dune sands were covered over by the sandstone and shale of the Morrison Formation, until a large scale marine transgression flooded the region in the Cretaceous. As sea levels fell, the Dakota Formation sands and pebbles took shape, followed by another marine transgression that deposited several thousand feet of shale as the Mancos Formation and Pierre Formation.

Lake Tulane in Florida is one of numerous natural lakes that occupy sinkholes, which were formed by the dissolution of Eocene limestone at depth. Lake Wales Ridge, within which Tulane Lake lies, is a linear highland that consists of unconsolidated quartz sands of the Pliocene Cypresshead Formation. These sands rest upon impermeable Miocene sediments that overlie limestone, which was dissolved by groundwater and collapsed to form Tulane Lake. It is oblong in shape, has a surface area of and has a maximum depth of .Beck, B. (1986) Sinkholes in Florida: an Introduction. Report No. 85-86-4.

Little Chell is situated south of Great Chell, lower down on the western ridge flank, alongside the grade II listed conservation area surrounding Victoria (or Tunstall) Park. Chell Heath lies east of both on the eastern flank, separated from Ball Green village by reclaimed spoil from Chatterley Whitfield Colliery. The landscaped spoil heap of the former Chatterley Whitfield mine, viewed across a lake of Whitfield Valley nature reserve. The superficial geology beneath Chell consist of Devensian glacial tills, which overlie the Middle and Upper Pennine Coal Measures; the same sequences of sandstones, mudstones and coal seams as forms the impressive coalfields of Lancashire.

Further evidence for this comes from the sand of the Tyee Formation that overlie the Roseburg Formation. Not only does this sand have the same isotopic composition of rock in the Idaho Batholith (and of sand now coursing down the Snake and Columbia Rivers), but it appears to have not been transported very far from its source. This implies that the Tyee Formation was much closer to the Idaho Batholith when it was deposited, and subsequently rotated away.; Geodetic surveys show that the region continues to rotate, likely as a result of extension of the Basin and Range Province.

British Geological Survey 1:50,000 scale geological map series (England and Wales) sheet no 314 Ringwood. 2004 The sands and clays of the Barton Group overlie those of the Bracklesham Group; in succession these are the Barton Clay, Chama Sand and Becton Sand formations. The Warren Hill Sand is a separately mappable ‘member’ within the Barton Clay as is the Becton Bunny Member within the Becton Sand. The uppermost and hence youngest of all the ‘solid’ rock units within the park is the Headon Formation (forming a part of the Solent Group, which comprises clays, silts, and sands laid down in freshwater conditions.

Sarir C is contained in a structural-stratigraphic trap, represented by dips to the east, south, and west and the major northeast-southwest-trending fault on its northwest flank. In much of the central and northwest, the reservoir subcrops and is sealed by shales that unconformably overlie it. Minor sand accumulations in the transgressive series above the basal sands occur in updip, pinchout traps. Sarir C's main trap is not full to the spill point, which is downplunge on the ridge west of the structure. The oil column has a maximum height of 91 m, with a 122 m vertical closure.

The rule of tincture does not apply to furs, nor to charges blazoned "proper" (displayed in their natural colour, which need not be a normal heraldic tincture).Fox-Davies, p. 86. The blazoning of a charge "proper" can therefore be used as a loophole when its natural coloration equates to or approaches another heraldic tincture it is desired to overlie. An example would be a white horse proper, since without breaking the rule of no metal on metal it could be placed on a field Or (gold), but a horse argent (silver horse), although visually indistinguishable, could not.

To their north and west are the similar lithologies of the Derwenlas Formation which can be seen for example beside the dam of Claerwen Reservoir. The Rhayader Mudstones overlie these and are to be found further north and west again forming such summits as Esgair Penygarreg, Moelfryn and Craig Dyfnant. North and west of Craig Goch Reservoir are the Rhuddnant Grits (Formation), the Pysgotwr Grits (Formation) and the Glanyrafon Formation, each of which comprises both sandstones and mudstones. They give rise to the knolly country around Teifi Pools and to such summits as Esgair y Llwyn in the east.

Lodge Pond, Alice Holt Forest The Forest is situated in the western Weald. It lies in the Gault clay vale that separates the chalk ridge which runs between Farnham and Alton from the malmstone (Greensand) hills or "hangers" (from the Old English hangra, wood on a steep slope) around Binsted. It occupies a low plateau with steeply sloping edges where deposits of stony Pleistocene drift, the remnants of ancient pre-glacial river terrace of the "Proto-Wey", overlie the heavy, wet Gault. Alice Holt Forest was noted for the oak woodlands that grew on its thick Gault clay.

During the fourth phase of eruptive activity 54,000 years ago, eruptions were again no longer subglacial. Lava flows from this phase of activity overlie pyroclastic deposits from the third phase of activity and ice-dammed lava from the second phase of activity. Between 54 and 30 thousand years ago, the fifth phase of eruptive activity occurred subglacially and produced two distinct types of lava-breccia associations. The first subglacial eruption between 54 and 40 thousand years ago produced lava domes and monomict breccia, while the other subglacial eruption between 40 and 30 thousand years ago took place under thinner glacial ice.

3D model of the volcano Ciomadul is located in the southeastern Carpathians, at the end of the Călimani (Kelemen) – Gurghiu (Görgényi) – Harghita (Hargita) volcanic chain, and is also known as Ciomadu. The gorge of the Olt River separates Ciomadul from the Harghita Mountains. The towns of Băile Tușnad and Bixad are close to the volcano, and a road leads up the volcano from the southeast and goes past the Mohos swamp to the St. Ana lake. The basement of the volcano is formed by flysch of Cretaceous age and by older volcanics; in some places volcanic rocks overlie fluvial deposits.

These rocks are exposed, along the north coast of St Brides Bay south of St Davids and in particular at Caer Bwdy Bay just southeast of the city where they are seen to overlie the Caerbwdy Sandstone Formation. They are exposed again in the sides of the ria at Solva and occur more widely inland of the village though exposures are less frequent. There are less extensive outcrops further west at St Justinian and on Ramsey Island. To the east they occur again north of Newgale and at Tancredston and to the west of Wolf's Castle.

The Hulcross Formation is part of the Fort St. John Group. Originally described as a member of the Commotion Formation, the Hulcross was elevated to formational status along with the other members of the Commotion by D.F. Stott in 1982, who proposed that the term 'Commotion Formation' be abandoned. The shales of the Hulcross abruptly overlie the sandstones of the Gates Formation and grade into the overlying sandstones of the Boulder Creek Formation. It is equivalent to the Harmon Member of the Peace River Formation in the Peace River plains to the east, and to the Wildhorn Member of the Scatter Formation in the Liard River region.

The Claymore field was discovered in 1974 by Occidental of Scotland with well 14/19-2 which penetrated 158 metres of oil sand at a depth of 2,459 metres subsea. The field is subdivided into main, central and northern areas. Production is from Upper Jurassic paralic and turbidite sandstones in the main area, lower Cretaceous turbidite sandstones that overlie faulted Graben margins in the northern area, and Permian carbonates and Carboniferous sandstones in the central area. The oil in place has an API Gravity of 26–33° and a gas oil ratio of 100–400 standard cubic feet per barrel. The sulpher content was 1.8 %.

The Keilor Plains, where the geomorphological and geological features of heritage value are located, is part of the greater Western Volcanic Plains which cover a large part of western Victoria and extend into south-eastern South Australia and are stated to be the third largest lava plains in the world. These landforms were created by the incision of the Jacksons Creek into thick lava flows that erupted about 2.5 to 2.8 million years ago during the Pleistocene Period. These lavas overlie steeply dipping Silurian sedimentary rocks. Sedimentary rock and fossils found in the park are also dated back 400 million years, an indication that the area was once a sea.

The Nyasiri tenement is located in northeast Tanzania within the historically productive Mara-Musoma Goldfield some 20 km SE of North Mara (Nyabirama) mine owned by Barrick Gold. The area is accessible by Tarime airstrip then a rough road going towards the Serengeti District; the tenement straddles the western border of the Serengeti National Park. The Nyasiri Project is hosted dominantly within granite that contains two small inliers of greenstone rocks (1 to 2 km and 2 to 3 km in area) presumably of Nyanzian origin. The western quarter of the property is covered with Bukoban Proterozoic-age sediments which unconformably overlie the Archean granite/greenstone beneath.

In all cases, the pools overlie acidic igneous rocks, and they are usually mineral-poor and retain some moisture in the sediment when they dry out. Like all Anostraca, T. stagnalis is a filter feeder, removing microplankton, microorganisms and other organic material from suspension with its bristly phyllopodia. Tanymastix stagnalis is sensitive to changes in the intensity of light, and respond to sudden shade by swimming towards the bottom of the pool, or even burying themselves in the sediment. The main threat to them is perturbation of the habitat, in particular the introduction of predators such as the fishes Lepomis gibbosus and Gambusia affinis.

In the simplest form, it is a practice for improvisation. The Six Viewpoints theory was adapted by directors Anne Bogart and Tina Landau over the course of 10 years, ultimately resulting in the delineation of nine "physical" Viewpoints and 5 "vocal" ones. Bogart and Overlie were on the faculty of ETW at NYU in the late 1970s and early 1980s, during which time Bogart was influenced by Overlie's innovations. Overlie's Six Viewpoints (space, story, time, emotion, movement, and shape) are considered to be a logical way to examine, analyze and create art in a profound way while Bogart's Viewpoints are considered practical in creating staging with actors.

Burou made a point of barring, but not damaging, the posterior aspect of the prostate so that the penile skin flap after invagination would immediately overlie this aspect, which he felt optimized the possibility of postoperative orgasm. The separation was extended digitally and was considered complete as soon as two fingers or a vaginal retractor could be admitted easily. Burou considered this first part of the operation to be the most important, but most risky, and stressed the importance of repeated intrarectal inspection to determine that there was no lesion to the rectal wall. He considered the second part of the operation to be relatively easy.

Constant onshore winds cool the lakeward side of the island and provide clean beaches with ideal swimming and boating conditions, but poor roads between Rusinga and the nearest town, Homa Bay, inhibit trade and tourism. The brightly glittering black sands of the beaches are made of crystals of melanite garnet, barkevikite hornblende, and magnetite eroded from the uncompahgrite lava fragments in the agglomerates that overlie the fossil beds. The island is also notable as the family home and burial site of Tom Mboya, who before his assassination in 1969 was widely pegged as Jomo Kenyatta's successor as President of the new nation of Kenya.

On the western side of the town centre the Blakewater continues through the Wensley Fold area before joining the River Darwen outside Witton Country Park; the Darwen flows into the River Ribble at Walton-le-Dale. The geology of the Blackburn area yields numerous resources which underpinned its development as a centre of manufacturing during the Industrial Revolution. Mineable coal seams have been used since the mid-late 16th century. The Coal Measures in the area overlie the Millstone Grit which has been quarried in the past for millstones and, along with local limestone deposits, used as a construction material for roads and buildings.

The Silurian is a major division of the geologic timescale that started about 443.8 ± 1.5 Ma. During the Silurian, Gondwana continued a slow southward drift to high southern latitudes, but there is evidence that the Silurian ice caps were less extensive than those of the late Ordovician glaciation. The melting of ice caps and glaciers contributed to a rise in sea levels, recognizable from the fact that Silurian sediments overlie eroded Ordovician sediments, forming an unconformity. Other cratons and continent fragments drifted together near the equator, starting the formation of a second supercontinent known as Euramerica. The vast ocean of Panthalassa covered most of the northern hemisphere.

It is assumed that the hillfort dates to the pre-Roman Iron Age. The date of the broch is uncertain but it has been speculated that it was built between the two main periods of Roman occupation in Scotland: some time in the 2nd century AD. Excavations at Torwoodlee Broch, also in the Scottish Borders, has shown that it was built and demolished during this period. Within the hillfort is an array of stone footings marking the positions of houses and other structures. Some of the houses overlie the defences – indicating that they are later than hillfort and may be later than the broch as well.

The Nervo Formation consists of rolling to locally hummocky plains that lie in intermassif depressions between the mountains formed by the Caloris Montes Formation. The plains generally lie within the annulus of rugged terrain marked by the Caloris Montes Formation and locally appear to drape and overlie some of the more low-lying massifs. The Nervo bears some resemblance to the Apennine Bench Formation around the Imbrium Basin;Hackman, R. J., 1966, Geologic map of the Montes Apenninus region of the Moon: U.S. Geological Survey Miscellaneous Investigations Series Map I-463, scale 1:1,000,000. its closest counterpart in Orientale is the knobby facies of the Montes Rook Formation.

Bolonchén, Mexico, used as source of water, 1842 In the north and northwest of the Yucatán Peninsula in Mexico, the cenotes generally overlie vertically extensive voids penetrating below the modern water table. However, very few of these cenotes appear to be connected with horizontally extensive underground river systems, with water flow through them being more likely dominated by aquifer matrix and fracture flows. In contrast, the cenotes along the Caribbean coast of the Yucatán Peninsula (within the state of Quintana Roo) often provide access to extensive underwater cave systems, such as Sistema Ox Bel Ha, Sistema Sac Actun/Sistema Nohoch Nah Chich and Sistema Dos Ojos.

The El Tatio ignimbrite ponded in the Tatio graben and may have originated at the Tocorpuri rhyolite dome, which is less than one million years old, in a vent now buried beneath the El Tatio volcanic group, or at the Laguna Colorada caldera. The El Tatio volcanic group has likewise been dated to be less than one million years old, and its lavas overlie the older formations. Volcan Tatio erupted mafic lavas probably during the Holocene; later this volcano was reinterpreted to be of Pleistocene age. Petrological data suggest that over time the erupted lavas of the El Tatio volcanic group have become more mafic, with older products being andesitic and later ones basaltic-andesitic.

Hayden gave the name "Santa Fe Marls" to the extensive sedimentary beds in the valley of the Rio Grande near Santa Fe during his 1869 survey of New Mexico and Colorado. He likened these to the badlands of South Dakota and correctly determined that they were upper Tertiary in age and were much younger than the Galisteo Formation beds which they overlie. He noted their great thickness, which he observed to be at least .Hayden 1869 By 1936, the Santa Fe Formation had been traced from central New Mexico into southern Colorado.Wilmarth 1936 Two years later, Bryan recognized that it extended at least from the San Luis Basin to beyond El Paso and was extensively faulted and deformed.

This group of dancers formed the core of an ensemble of improvising dancers that came to be known as The Grand Union, a group that also came to include Trisha Brown. The Grand Union toured extensively in the early 1970s; while in the group Dilley performed pieces by other members as well as her own works, including “The Sapsuckersummer Dance” series at Cornell Summer Dance Group in 1970, “Wonder Dances” (1975) and “To the Golden Gate Bridge” from her dance series “Coast” (1968-1971). In 1972, Dilley founded her own improvisational dance company, an all woman group called The Natural History of The American Dancer including Carmen Beauchat, Cynthia Hedstrom, Judy Padow, Mary Overlie, Rachel Lew and Suzanne Harris.

These inlays offered many potential advantages over the standard LASIK technique, the most significant of which is that the inlay procedure is reversible.Examples of these inlays can be found in US Patents: #6,203,538, granted March 2001, #6,217,571, granted April 2001, AND #6,280,470, all entitled, "INTRASTROMAL CORNEAL MODIFICATION"; #6,221,067, granted April 2001, entitled "CORNEAL MODIFICATION VIA IMPLANTATION"; and others However their ablation was not predictable. In October 2009 Peyman invented and applied for a patent on a method of preventing corneal implant rejection, which was approved in 2017 (US Patent 9,681,942). It consisted of forming a Lasik flap in the cornea, raising the flap, inserting a lamellar cornea under the flap so as to overlie the exposed stromal tissue.

Otoconia are crystals of calcium carbonate and make the otolithic membrane heavier than the structures and fluids surrounding it. The otoconia are composite crystallites that overlie the macular sensory epithelium of the gravity receptors of most vertebrates and are required for optimal stimulus input of linear acceleration and gravity. Fishes often have a single large crystal called an otolith, but otoconia from higher vertebrates have numerous crystals, and each apparently single crystal in fact has multiple crystallites that are composed of organic and inorganic components. Ultra-high resolution transmission electron microscopy of rat otoconia shows that the crystallites are 50-100 nm in diameter, have round edges and are highly ordered into laminae.

Some of the best outcrops for these rocks are on the west side of the southern Sacramento Valley at Putah Creek and Cache Creek canyons. The formation names used here extend to the subsurface where several gas wells in the center of the valley produce from the same rocks, and from younger rocks that overlie them. Although the younger rocks are not exposed in the canyons to the west, most geologists combine the formation names from the west side outcrops with the subsurface names from the gas fields to create a coherent set of names that is largely agreed upon for most of the Sacramento Valley.Ingersoll and Dickinson (1990) in their Table 2 on p.

Until the post-war period Tottington was a ribbon development along the Bury to Blackburn road, the Kirklees Valley to the east stopped development in that direction and kept Tottington distinct from Brandlesholme. Within the Kirklees Valley there are a number of artificial mill ponds and reservoirs created during Tottington's industrial heyday. Many of these have since dried up, but the remaining examples have proven an ideal habitat for numerous species of wildfowl and bats.Bat Activity Survey over millponds in South Lancashire South Lancashire Bat Group The superficial geology beneath Tottington consists of Devensian glacial tills, which overlie the Lower Pennine Coal Measures; the same sequences of sandstones, mudstones and coal seams that form the Lancashire Coalfield.

One of the most noteworthy aspects of Newfoundland geology is a result of the constant movement of tectonic plates. Approximately 500 million years ago the action of these plates forced parts of the oceanic crust beneath the Iapetus Ocean up and over the eastern margin of the North American plate. Sections of oceanic crust which overlie continental crust are known as ophiolites. Gros Morne National Park was designated a UNESCO World Heritage Site because it is one of the best places in the world to see the effects of plate tectonics and one of the few places where rocks formed at the Mohorovicic Discontinuity between the crust and the upper mantle of the Earth can be seen.

Historically, the central business district in Tampico stretched one block, the 100 block, of Main Street, which extended from Market Street on the north to the Chicago, Burlington and Quincy tracks on the south. The boundaries of the historic district mostly overlie the traditional boundaries of the central business district The district boundaries exclude properties that are not part of the historic period. In addition, the boundaries exclude residential properties. The northern boundary of the historic district, near Market Street, was drawn to include the properties at 106 and 107 S. Main while excluding a lot, vacant at the time of the district's inclusion on the National Register, and a new building.

Fir Creek, a Bull Run River tributary Columbia River basalts, 10 to 20 million years old, that underlie much of the Bull Run watershed are exposed near the bottoms of steep canyons along the river and its tributaries. In the western half of the watershed, the Rhododendron formation, rich in sediments, overlies the basalt, and later volcanic flows of basalt and andesite overlie both older formations. Areas of thick talus occur in the eastern part of the watershed at elevations higher than above sea level, and north-facing slopes above show evidence of glaciation. Over many centuries, streams in the watershed have carved canyons through the Rhododendron formation to the level of the basalt.

Of particular interest is the somewhat broader range of approximately 53 to 48 Ma for Crescent Formation basalts on the east side of the Olympic Peninsula that overlie the Blue Mountain unit, reliably dated at 48 Ma or younger. calculated a maximal depositional age of about 48.7 Ma, while report four ages ranging from 44.7 Ma to 47.8 Ma. This structural relationship was previously understood as showing that Siletzia – or at least its northern end – was built on the continental margin. It is now argued. that the unconformity of ages can be explained by the Blue Mountain unit being thrust under Siletzia some time after 44.5 Ma, and shows that Siletiza was not necessarily emplaced along the continental margin.

The terraces of the Trabancos River only occur on the left hand side of the valley. Their sediments overlie Miocene sediments. This is the result of a hard slope in the opposite margin, where the terrain is heavily eroded, which renders the formation and maintenance of river terraces impossible. fault that affects the middle and final courses of the Trabancos River as well as the sequence of its river terraces Of the previously mentioned river terraces, the one known as TT-4 is only visible near Narros del Castillo (Ávila). Terrace TT-3 is the best preserved of the lot; although its height on the bed of the stream is not constant, it clearly stands out on the floodplain.

The subacromial bursa is the synovial cavity located just below the acromion, which communicates with the subdeltoid bursa in most individuals, forming the so-called subacromial-subdeltoid bursa (SSB). The SSB bursa is located deep to the deltoid muscle and the coracoacromial arch and extends laterally beyond the humeral attachment of the rotator cuff, anteriorly to overlie the intertubercular groove, medially to the acromioclavicular joint, and posteriorly over the rotator cuff. The SSB decreases friction and allows free motion of the rotator cuff relative to the coracoacromial arch and the deltoid muscle. French anatomist and surgeon, Jean-François Jarjavay is credited as the first to describe morbid processes of the SSB in 1867.

Caledonian schist and gneiss form a hard cap at the top of Saivaara (a mountain in Enontekiö) covering the sedimentary rocks of the lower part of the mountain The youngest rocks in Finland are those found near Kilpisjärvi in Enontekiö (the northwesternmost part of the country's northwestern arm).Puustinen, K., Saltikoff, B. and Tontti, M. (2000) Metallic Mineral Deposits Map of Finland, 1:1 million, Espoo, Geological Survey of Finland These rocks belong to the Scandinavian Caledonides that assembled in Paleozoic times. During the Caledonian orogeny Finland was likely a sunken foreland basin covered by sediments; subsequent uplift and erosion would have eroded all of these sediments. In Finland, Caledonian nappes overlie shield rocks of Archean age.

In the east, between Haflong and Dauki, the beds north of the fault are mostly horizontal or dip gently down to the south, while those of the south of the fault dip more steeply and in places are nearly vertical. There is extensive shattering in a belt several kilometres wide along the fault. West of Haflong, where the fault has little stratigraphical throw, the geosynclinal facies of the Eocene approaches within 7 km of the Kopili beds which are part of the calcareous shelf facies of the Eocene, and which immediately overlie the Sylhet Limestone. In the North Cachar Hills it overrides all the lower thrusts to rest directly on the Foreland Spur.

They performed at the Whitney Museum on April 29, 1972 as well as at Bennington College, Oberlin College and other venues. That same year, Dilley participated in the first public performance of Contact Improvisation at the Weber Gallery with Steve Paxton. In 1974, Dilley cofounded Danspace Project at St. Mark's Church in-the-Bowery with New York School poet Larry Fagin and choreographer Mary Overlie. Also in 1974, Tom Hast, who had seen the Whitney performance and danced with Dilley in the Weber Gallery performance, invited her to teach at the first summer session of the Naropa Institute in Boulder, Colorado, at the conclusion of which she was put in charge of designing a dance and movement program for the institute.

The Rocky Mountain thrust and fold belt propagated from west to east, accommodating up to of horizontal shortening near the Canada and US border, and about in northern parts of BC and Montana. The eastern boundary of the fold and thrust belt is marked by the easternmost deformed strata known in outcrop and or in the subsurface. Because strata underlying the Alberta plains is gently dipping, it is difficult to pinpoint the edge of deformation on this side of the belt. On the west side, the Rocky Mountains are bounded by the Rocky Mountain Trench, where the trench is interpreted to overlie the western, down-dropped blocks of major normal faults that separate the southern Rocky Mountains from the Purcell mountains.

The bed rock of the whole basin consists of the limestones and schists of the Nome group, including many veins and stringers of quartz, some of which are known to be auriferous (gold-bearing). The river occupies a broad and deeply gravel-filled valley, in the floor of which the stream bed is trenched to a depth of , leaving well-marked gravel terraces and benches through nearly the whole length. In the lower part of the valley, the stream has cut to bed rock through the gravel deposits in only a few places, but in the headwaters region the gravels overlie broad rock-cut lynches on both banks. Dawson Gulch joins the river nearly opposite Big Four Creek, which is named after its first four prospectors.

Overlying the Jurassic is a Cretaceous sequence whose lowermost unit is the Wealden Group comprising mudstones, limestones, siltstones and sandstones and which extends in a band from Hunstanton southwards to south of the village of Southery. A narrow band of sandstone immediately east of this constitutes the Lower Greensand Group and beyond this, and stratigraphically above it, lie the mudstones and sandstones of the Gault and Upper Greensand formations. The Grey Chalk and the White Chalk subgroups and the Hunstanton Formation overlie the Greensand. The Chalk extends across the rest of Norfolk east of a wavering line from Holme- next-the-Sea on the north coast to Hockwold cum Wilton on the Suffolk border though it is concealed beneath later Neogene sediments in the east.

Green Mound is one of the largest Pre-Columbian shell mounds, or shell middens, in the United States. Located in Ponce Inlet, Florida, the peak of the mound is the highest elevation in the small city. While it once stood at forty feet above sea level, a combination of public works projects on the nearby roads and natural erosion have reduced the height of the mound by about 10 feet. The mound was built by Native Americans of the late St. Johns II cultural period, as indicated by the finding of pre-Columbian "chalky ware" ceramics dating to later than 800 AD. These overlie earlier relics of the St. Johns I cultural period, the cultural period following the Archaic period.

Sunken road or via cava Several important and unimportant Roman roads, such as the Via Cassia, overlie Etruscan precursors, but there are sufficient Etruscan sites that were neglected after their conquest to allow an understanding of the considerable Etruscan road system. Roads did not just run between cities, but out into the countryside to allow agricultural produce to be easily brought in.Izzet, 193–195 While not as heavily engineered as Roman roads, considerable efforts went into creating a road surface that on major routes could be as wide as 10.4 metres, on a 12 kilometre stretch connecting Cerveteri with its port Pyrgi, made in the 5th century. This had a gravel surface, between tufo edging-blocks, and a central drainage channel.

The breast: cross- section scheme of the mammary gland. In women, the breasts overlie the pectoralis major muscles and usually extend from the level of the second rib to the level of the sixth rib in the front of the human rib cage; thus, the breasts cover much of the chest area and the chest walls. At the front of the chest, the breast tissue can extend from the clavicle (collarbone) to the middle of the sternum (breastbone). At the sides of the chest, the breast tissue can extend into the axilla (armpit), and can reach as far to the back as the latissimus dorsi muscle, extending from the lower back to the humerus bone (the bone of the upper arm).

The Enon Formation was formed along the southern section of South Africa during the break up of Gondwana when there was widespread erosion of rocks comprising the Cape Fold Belt. It is considered to be Late Jurassic to Early Cretaceous in age although more thorough dating needs to be undertaken. It provides important geological data on the change in landscape during the break-up of Gondwana in relation to the younger and softer formations - the Kirkwood and Sundays River - which overlie it, and because it is the oldest formation of the onshore post-Karoo Mesozoic deposits found in South Africa. Underlying strata are separated by unconformities in most locales expect where the Enon is underlain by deposits of the Cape Fold Belt.

Drawing (1906) of the excavated Lapis Niger in the Roman Forum, in Rome, Italy. Visible are the sacellum (miniature shrine; left), the truncated tufa column (right) and the rectangular stele with inscriptions (behind column stub). The Lapis Niger (Latin, "Black Stone") is an ancient shrine in the Roman Forum. Together with the associated Vulcanal (a sanctuary to Vulcan) it constitutes the only surviving remnants of the old Comitium, an early assembly area that preceded the Forum and is thought to derive from an archaic cult site of the 7th or 8th century BC. The black marble paving (1st century BC) and modern concrete enclosure (early 20th century) of the Lapis Niger overlie an ancient altar and a stone block with one of the earliest known Latin inscriptions (c.

Trask and Guest concluded that the surface of these plains represents a primordial surface of Mercury on which craters have been superposed. The large extent of this surface compared to its counterpart on the Moon was thought to reflect the restricted distribution of ejecta around each individual crater caused by the relatively high gravity on Mercury. Because of this high gravity, considerable areas were unaffected by crater and basin ejecta. However, Malin and Guest and O’Donnell (1977) have shown that in some areas the intercrater plains overlie highly degraded craters, a relation suggesting either that the intercrater plains were formed during a specific time in Mercury’s history and that cratering occurred both before and after their emplacement, or, alternatively, that the intercrater plains were formed by a continuous process throughout cratering history.

Hudson Bay occupies a large structural basin, known as the Hudson Bay basin, that lies within the Canadian Shield. The collection and interpretation of outcrop, seismic and drillhole data for exploration for oil and gas reservoirs within the Hudson Bay basin found that it is filled by, at most, of Ordovician to Devonian limestone, dolomites, evaporites, black shales, and various clastic sedimentary rocks that overlie less than of Cambrian strata that consist of unfossiliferous quartz sandstones and conglomerates, overlain by sandy and stromatolitic dolomites. In addition, a minor amount of terrestrial Cretaceous fluvial sands and gravels are preserved in the fills of a ring of sinkholes created by the dissolution of Silurian evaporites during the Cretaceous Period.Burgess, P.M., 2008, Phanerozoic evolution of the sedimentary cover of the North American craton.

Acidic Soils: These acidic soils are derived from the granite upland areas of the Richardson Peak Mountains Land System that form the western slopes of the Bladen Basin. These steep mountainous slopes of the Maya Mountains – over 25° angle between altitude, overlie Santa Rosa Group metasediment rocks, producing non-alluvial, shallow soils on the slopes, or deeper colluvial deposits that collect at the base of the hillslopes following erosion. Vegetation characteristic of this soil type is evergreen broadleaf forest, shrubland and pine at higher altitudes. Recent Soils: The most recent soils are in the north-east of Bladen, following the line of the floodplain of Bladen Branch and Richardson Creek, and laid down by these streams as they drain the Richardson Peak Mountains and karst hills to either side, and also the volcanic porphyrite.

Active lavaka on right, with inactive, largely infilled older lavakas to left Lavaka, the Malagasy word for "hole", usually found on the side of a hill, is a type of erosional feature common in Madagascar. However, lavakas have also been found in South Africa, the Democratic Republic of the Congo, and South Carolina, and similar landforms have been found in Brazil, the Great Plains of the U.S., and Swaziland. They are most common in tropical regions between the Cancer and Capricorn latitudes, especially the Central Highlands of Madagascar, where approximately one metre thick laterites develop on steep terrains in a monsoonal climate. Lavakas form where these hard laterites overlie thick (tens of metres) saprolite, on steep (35 to 55 degree) slopes, in areas that have a hot dry season and a warm wet season.

The Ordos Desert forms an intermediate step in the descent from the Himalayas to the lowlands of eastern China. Towards the south it rises to an altitude of over 1,500 m, and in the west, along the right bank of the Yellow River, the Arbus or Arbiso Mountains, which overlie the steppe by some 900 m, serve to link the Helan Mountains with the Yin Mountains. The northern part of the great bend of the Yellow River is filled with the sands of Kuzupchi River, a succession of dunes, 12-15 m high. In some places these sand-dunes approach close to the Yellow River; in others they are parted from it by a belt of sand, intermingled with clay, which terminates in a steep escarpment, 15 m and in some localities 30 m above the river.

The Quaternary-age Casiri is one of the youngest volcanic systems in southern Peru with postglacial activity, and Peru's southernmost Holocene volcano. Holocene lavas sourced from fissure vents overlie Pleistocene-age moraines and are uneroded; radiometric dating on the volcano has yielded ages of 50,000 years and surface exposure dating carried out more recently has found ages of 6,000 ± 900 and 2,600 ± 400 years for two dark lava flows southwest and south of Casiri's main summit, respectively. There are no reported eruptions, but activity may or may not have occurred in historical time; Casiri does feature hot springs and solfataras, and has been classified as a latent or potentially active volcano with a moderate threat level. In 2012, the Geophysical Institute in Peru announced that it would begin monitoring Casiri, along with two other volcanoes in southern Peru, with seismometers.

The "Agnes Banks Sand" is described as a stratigraphic unit of Pliocene of Pleistocene age (7 million-300,000 years ago) and probably a fluvial deposit which has been redistributed by westerly winds. The sands are surrounded by and overlie lateritized tertiary alluvial deposits, mainly clay and silts which make up the Cumberland Plain to the south and east. The sand deposit is unique in that although it is from the present coast, it supports unusual vegetation in many ways similar to coastal sand dune vegetation such as Myall Lakes, and with affinities also to Hawkesbury sandstone vegetation which is located in the Sydney Basin. The deposits themselves are highly important scientifically: as a reference site for understanding the past climatic history of the region; and, for comparison of the vegetation with similar vegetation on coastal sand deposits.

Banded iron formation in the North Pit area of Sherman Mine, showing the red lateral lines of jasper and grey lateral lines of magnetite typical of Neoarchean (2,800–2,500 million year old) banded iron formations Layered chert-magnetite and lesser chert-pyrite-pyrrhotite iron formations are located at the base of the Arsenic Lake Formation. Former drilling near Vermilion Lake and spatial relationships observed on the surface, suggest that the sulfide-rich iron formation lies up to stratigraphically under the oxide facies iron formation. Iron production from the West and North Pits of Sherman Mine came from this chert-magnetite iron formation unit while chert-magnetite iron formations at the South and East Pits compose the Turtle Lake Formation. The South and East Pit iron formations reach thicknesses of and overlie a thinly bedded turbidite package on the southern limb of the Tetapaga Syncline.

The distinctive landslip viewed from the south The distinctive shape of this Old Red Sandstone hill comprises a long ridge oriented nearly north–south, with a jagged western side resulting from ice age landslips . The upper slopes of the hill are composed of Devonian age sandstones assigned to the Senni Formation (formerly known as the "Senni Beds"). These overlie weaker mudstones of the St Maughans Formation - a situation which has contributed to the instability of the hill's steep flanks, resulting in a very large landslip at the northern end of the mountain, although the British Geological Survey map of the area (Abergavenny sheet) shows the landslide extending along the whole of the west side of the mountain. There are numerous other landslips of a similar nature on the nearby hills, although that on the Skirrid is perhaps the most well known owing to its visibility from several directions.

In a typical configuration, DLC remote terminals are installed in new neighbourhoods or buildings as a means of reducing the labour and complexity of installing individual local loops from the customer to the central office (CO). A fibre optic cable or several copper pairs for the whole system from the CO to the DLC remote terminal replace the individual pair previously needed for each loop. DLC remote terminals are typically stored in Serving Area Interfaces–metal cabinets alongside or near roadways that overlie communications rights-of-ways. With the growth in popularity of digital subscriber line (DSL) and the benefits provided by shorter metallic loops used with DLC systems, digital loop carriers are sometimes integrated with digital subscriber line access multiplexers (DSLAM), both systems then taking advantage of the digital transmission link from the DLC to the CO. Fibre in the loop (FITL) systems are functionally equivalent to DLC.
