Retreat Hills
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. Geography The Aviator Glacier forms on the plateau of Victoria Land and flows in a generally southward direction along t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Névé
Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow can contribute to glacier formation through the process of ''nivation''. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice that glaciers are composed of. Glacier formation can take years to hundreds of years, depending on freeze-thaw factors and snow-compaction rates. Névé is annually observed in skiing slopes, and is generally disliked as an icy falling zone. Névé has a minimum density of 500 kg/m3, which is Density#Water, roughly half of the density of liquid water at 1 Atmosphere (unit), atm. Névé can also refer to the Alpine climate, alpine region in which snowfall accumulates, becomes névé, and feeds a glacier. See also * Suncup (snow), Suncup Notes External links * Névés, ...

Deception Plateau
The Mountaineer Range () is the range of mountains lying between the Mariner Glacier and Aviator Glacier in Victoria Land, Antarctica. It lies to the south of the Victory Mountains and northeast of the Southern Cross Mountains. Exploration and naming The seaward parts of the Mountaineer Range were first viewed by James Clark Ross in 1841, and subsequently by several British and later American expeditions. The precise mapping of its overall features was accomplished from United States Navy air photographs and surveys by New Zealand and American parties in the 1950s and 1960s. The range was named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, in keeping with the backgrounds of members of the 1957–58 and 1958–59 field parties who made a reconnaissance of the area, and also in association with the names "Aviator" and "Mariner".

Mount Overlord
Mount Overlord is a very large mountain which is an extinct stratovolcano, situated at the northwest limit of Deception Plateau, 50 miles inland from the Ross Sea and just east of the head of Aviator Glacier in Victoria Land. Its asymmetrical cone is on the edge of a plateau above Aviator Glacier. While most of the cone is ice-covered, Mount Overlord does have a diameter caldera. Volcanic rocks from the western slope have been dated to about seven million years, so the volcano is thought to be extinct. It was so named by the northern party of New Zealand Geological Survey Antarctic Expedition The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s. Features named by the expeditions 19 ... (NZGSAE), 1962–63, because it "overlords" lesser peaks in the area.

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 ...
