Bennett Platform
Bennett Platform () is a high, nearly flat, snow-free mesa of dark rock of Antarctica, about long and wide, located immediately east of Mount Black, on the west side of Shackleton Glacier. Discovery and naming Bennett Platform was discovered and photographed by U.S. Navy Operation Highjump (1946–47), on the flights of February 16, 1947, and named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Floyd Bennett, copilot on the Byrd North Pole Flight of May 1926. Location Bennett Platform is on the west side of Shackleton Glacier opposite the point where Logie Glacier joins it from the east through a gap in the Cumulus Hills. Gallup Glacier runs along its north side. Features include Mount Black in the west and Matador Mountain in the east. Nearby features include Mount Rosenwald to the northwest, Mount Heekin to the north and Half Century Nunatak to the south. Features and nearby features Mount Black .

Mesa
A mesa is an isolated, flat-topped elevation, ridge, or hill, bounded from all sides by steep escarpments and standing distinctly above a surrounding plain. Mesas consist of flat-lying soft sedimentary rocks, such as shales, capped by a resistant layer of harder rock, like sandstone or limestone, forming a caprock that protects the flat summit. The caprock may also include dissected lava flows or eroded duricrust. Unlike a ''plateau'', which is a broader, elevated region that may not have horizontal bedrock (e.g., Tibetan Plateau), a mesa is defined by flat-lying strata and steep-sided isolation. Large, flat-topped plateaus with horizontal strata, less isolated and often part of extensive plateau systems, are called '' tablelands''. A ''butte'' is a smaller, eroded mesa with a limited summit, while a '' cuesta'' has a gentle dip slope and one steep escarpment due to tilted strata.Duszyński, F., Migoń, P. and Strzelecki, M.C., 2019.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Shackleton Glacier
Shackleton Glacier () is a major Antarctic glacier, over long and from wide, descending from the Antarctic Plateau from the vicinity of Roberts Massif and flowing north through the Queen Maud Mountains to enter the Ross Ice Shelf between Mount Speed and Waldron Spurs. Discovered by the United States Antarctic Service (USAS) (1939–41) and named by the Advisory Committee on Antarctic Names (US-ACAN) for Sir Ernest Shackleton, British Antarctic explorer. Course The Shackleton Glacier originates in the East Antarctic Ice Sheet and flows northeast between Dismal Buttress to the northwest and Roberts Massif to the southeast. It is joined from the right (east) by Zaneveld Glacier, which also originates in the ice sheet. Further north it is joined from the right by the Logie Glacier, which flows west through the Cumulus Hills. Flowing north, the Shackleton Glacier is joined from the left (west) by the Gallup Glacier and the Baldwin Glacier and from the right (east) by McGregor ...

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] |
Floyd Bennett
Floyd Bennett (October 25, 1890 – April 25, 1928) was a United States Naval Aviator who, along with then USN Commander Richard E. Byrd, made the first flight to the North Pole in May 1926. However, their claim to have reached the pole is disputed. Biography Bennett was born in Warrensburg, New York, in 1890. He was an automobile mechanic before he enlisted in the Navy in 1917, during World War I. Bennett attended flight school, learned to fly and was rated as an Aviation Pilot. Bennett served with Richard E. Byrd on an aviation survey of Greenland in 1925, on which Byrd came to respect his ability as a pilot. North Pole flight Byrd named Bennett as his pilot for an attempt to reach the North Pole by air in 1926. The expedition was financed by John D. Rockefeller Jr., Edsel Ford, Vincent Astor, Rodman Wanamaker and T.F. Ryan. Bennett was at the controls on May 9 as the two men made their attempt, in a Fokker tri-motor called the ''Josephine Ford''. They returned to the ...

Richard E
Richard is a male given name. It originates, via Old French, from compound of the words descending from Proto-Germanic language">Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include " Richie", " Dick", " Dickon", " Dickie", " Rich", " Rick", "Rico (name), Rico", " Ricky", and more. Richard is a common English (the name was introduced into England by the Normans), German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish.

Cumulus Hills
The Cumulus Hills () are several groups of largely barren hills in Antarctica. Divided by the Logie Glacier, they are bounded by Shackleton Glacier on the west, McGregor Glacier on the north and Zaneveld Glacier on the south. Discovery and naming The exposed rock in this area was observed on a number of occasions to give rise to the formation of cumulus clouds, considered to be very rare at this elevation. The hills were named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition (1961–62) because of these clouds. Features The Cumulus Hills are bounded by the Shackleton Glacier to the west, Zaneveld Glacier to the south and McGregor Glacier and Gatlin Glacier to the north. There is a large snowfield to the east. From south to north, features include Schroeder Hill, Wiest Bluff, Vickers Nunatak and Ellis Bluff, all south of Logie Glacier, which flows west into Shackleton Glacier. North of this are Landry Bluff, separated by Brunner Glacier from Hal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
