Pinnacle Gap
The Mesa Range () is a range of flat-topped mesas comprising the Sheehan, Pain, Tobin and Gair Mesas, situated at the head of the Rennick Glacier in Victoria Land, Antarctica. It was given this descriptive name by the northern party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) of 1962–63. Location The Gair, Tobin and Pain mesas are in the east side of the middle reach of the Rennick Glacier, and the Sheehan Mesa is on the west side. The Monument Nunataks are to the northwest, the Freyberg Mountains to the north, Half-ration Névé and the larger Evans Névé to the northeast, the Southern Cross Mountains to the east, and the Deep Freeze Range to the south. Sheehan Mesa . A prominent mesa standing west-northwest of Pain Mesa in the northwest part of Mesa Range. Named by the northern party of NZGSAE, 1962–63, for Maurice Sheehan, field assistant with this party. Silva Ridge . A ridge leading to the top of Sheehan Mesa, on the northeast side. ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78th parallel south, 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Victoria of the United Kingdom, Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. History Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 Meteorite, meteorites in Antarctica, some of which were found near the Allan Hills in Victoria Land. The meteorites appeared to have undergone little change since they were formed at what scientists believe was the birth of the Solar System. In 1981, Lichen, lichens fo ...

Campbell Glacier
Campbell Glacier () is a glacier, about long, originating near the south end of Mesa Range and draining southeast between the Deep Freeze Range and Mount Melbourne to discharge into north Terra Nova Bay in Victoria Land, Antarctica. Location Campbell Glacier forms in the Southern Cross Mountains to the south of Gair Mesa and Suture Bench. It flows south past both sides of Mericle Rock, and is joined from the west by Rainey Glacier. Hedge Terrace forms its eastern side in this section.

Aeronaut Glacier
The Aviator Glacier () is a major valley glacier in Antarctica that is over long and wide, descending generally southward from the plateau of Victoria Land along the west side of Mountaineer Range, and entering Lady Newnes Bay between Cape Sibbald and Hayes Head where it forms a floating tongue. Exploration and naming The glacier was photographed from the air by Captain W.M. Hawkes, United States Navy, on the historic first flight from New Zealand to McMurdo Sound on December 17, 1955. An attempt to reconnoiter it by helicopter and to land a party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE) on it had to be abandoned when USS ''Glacier'' was damaged in pressure ice in December 1958. It was named by NZGSAE, 1958–59, as a tribute to the hazardous work of pilots and other airmen in Antarctic exploratory and scientific operations.

Frustum
In geometry, a ; (: frusta or frustums) is the portion of a polyhedron, solid (normally a pyramid (geometry), pyramid or a cone (geometry), cone) that lies between two parallel planes cutting the solid. In the case of a pyramid, the base faces are polygonal and the side faces are trapezoidal. A ''right frustum'' is a right pyramid or a right cone truncation (geometry), truncated perpendicularly to its axis; otherwise, it is an ''oblique frustum''. In a ''truncated cone'' or ''truncated pyramid'', the truncation plane is necessarily parallel to the cone's base, as in a frustum. If all its edges are forced to become of the same length, then a frustum becomes a ''Prism (geometry), prism'' (possibly oblique or/and with irregular bases). Elements, special cases, and related concepts A frustum's axis is that of the original cone or pyramid. A frustum is circular if it has circular bases; it is right if the axis is perpendicular to both bases, and oblique otherwise. The height of a f ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Evans Névé
Rennick Glacier () is a broad glacier, nearly long, which is one of the largest in Antarctica. It rises on the polar plateau westward of Mesa Range and is wide, narrowing to near the coast. It takes its name from Rennick Bay where the glacier reaches the sea. Early exploration The seaward part of the glacier was photographed by United States Navy Operation Highjump, 1946–47. The upper reaches of the Rennick Glacier were discovered and explored by the U.S. Victoria Land Traverse (VLT) in February 1960, and the first ascent made of Welcome Mountain by John Weihaupt, Alfred Stuart, Claude Lorius and Arnold Heine of the VLT party. On February 10, 1960, Lieutenant Commander Robert L. Dale, pilot of U.S. Navy (USN) Squadron VX-6, evacuated the VLT from , on this glacier, and then conducted an aerial photographic reconnaissance to Rennick Bay on the coast before returning the VLT team to McMurdo Station.
