Cameron Nunataks
The Cameron Nunataks () are a small cluster of nunataks rising above the west margin of Evans Neve, at the southern end of the Freyberg Mountains. The cluster was mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1960–64, and named by the Advisory Committee on Antarctic Names for Roy E. Cameron, biologist at McMurdo Station McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the Unit ..., summers 1966–67 and 1967–68. References * Nunataks of Antarctica Landforms of Adélie Land {{AdélieLand-geo-stub ...

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evans Neve
Rennick Glacier is 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. The seaward part of the glacier was photographed by U.S. Navy (USN) 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 7238S, 16132E, on this glacier, and then conducted an aerial photographic reconnaissance to Rennick Bay on the coast before returning the VLT team to McMurdo Station.

Freyberg Mountains
The Freyberg Mountains () are a group of mountains in Victoria Land, Antarctica, bounded by Rennick Glacier, Bowers Mountains, Black Glacier, and Evans Neve. Named for New Zealand's most famous General, Lord Bernard Freyberg, by the Northern Party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963-64. This mountain group includes the Alamein Range. These topographical features all lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. Key mountains * Mount Baldwin () is a mountain 5 nautical miles (9 km) southeast of Smiths Bench, in the Freyberg Mountains. Named by Advisory Committee on Antarctic Names (US-ACAN) for T.T. Baldwin, transport specialist, a member of the United States Antarctic Research Program (USARP) Victoria Land Traverse Party which surveyed this area in 1959-60. * Buttress Peak () is a peak at the east end of the central ridge of Gallipoli Heights. The descriptive name was suggested by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

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] |
McMurdo Station
McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the area ...
