Mount Webster (Antarctica)
The Harold Byrd Mountains () are a group of exposed mountains and nunataks which extend in an east–west direction between the lower part of Leverett Glacier and the head of the Ross Ice Shelf in Antarctica. They were discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by Rear Admiral Richard E. Byrd for D. Harold Byrd, a cousin of his and a contributor towards the purchase of furs for the expedition. Location The Harold Byrd Mountains are in relatively flat country to the northeast of the lower reaches of the Leverett Glacier, and to the south of the Ross Ice Shelf. Features include, from west to east, Mount Fridovich, Supporting Party Mountain, Mount Graham, Mount Nichols, Mount Manke, Cresley Peak and Fadden Peak. The Fallone Nunataks are to the north, and the Bender Mountains are to the east. Mount Webster is to the south. Features Mount Fridovich .

Nunatak
A nunatak (from Inuit language, Inuit ) 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 often form natural pyramidal peaks. Isolated nunataks are also called glacial islands, and smaller nunataks rounded by glacial action may be referred to as rognons. The word is of Greenlandic language, Greenlandic origin and has been used in English since the 1870s. Description The term ''nunatak'' is typically used in areas where a permanent ice sheet is present and the ridge protrudes 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 are isolated, they can also form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, hampering the formation of glacial ice on thei ...

Leverett Glacier
The Leverett Glacier () is about long and wide, flowing from the Antarctic Plateau to the south end of the Ross Ice Shelf through the Queen Maud Mountains. It is an important part of the South Pole Traverse from McMurdo Station to the Admundson–Scott South Pole Station, providing a route for tractors to climb from the ice shelf through the Transantarctic Mountains to the polar plateau. Discovery and naming The Leverett Glacier was discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by him for Frank Leverett, an eminent geologist at the University of Michigan and an authority on the glacial geology of the central United States. Course The Leverett Glacier forms on the polar plateau to the west of the California Plateau. The Stanford Plateau is to the east. It flows north through the Watson Escarpment between Mount Beazley to the west and McLean Peak to the east, then turns to flow in a north-north-west directi ...

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of the Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island, Antarctica, Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after James Clark Ross, Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Byrd Antarctic Expedition
Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an United States Navy, American naval officer, and pioneering aviator, polar explorer, and organizer of polar logistics. Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica. Byrd claimed to be the first to reach both the North Pole, North and South Poles by air. However, there is some controversy as to whether Byrd was actually the first person to reach the North Pole. It is generally believed that the distance Byrd claimed to fly was longer than the possible fuel range of his airplane. He was a List of Medal of Honor recipients during peacetime, recipient of the Medal of Honor, the United States Armed Forces' highest military decoration, and the Navy Cross, the second highest honor for valor given by the U ...

Bender Mountains
The Bender Mountains () are a small group of mountains southwest of the Berry Peaks, between the southeast edge of the Ross Ice Shelf and the Watson Escarpment. Exploration and naming The Bender Mountains were mapped by the United States Geological Survey (USGS) from ground surveys and from United States Navy air photos, 1960–63. They were named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Commander Leslie C. Bender, U.S. Navy, an aircraft commander at McMurdo Station, 1962–63 and 1963–64.} Location The Bender Mountains are in a generally flat area south of the Ross Ice Shelf and west of the Reedy Glacier, which enters the ice shelf to the north of the mountains. They are south of the Watson Escarpment and east of the Harold Byrd Mountains, which in turn are east of the Leverett Glacier. Features of the mountains include Mount Fiedler and Mount Mahan. To the northeast are the Berry Peaks including Scallop Ridge and Gallaher Peak. McCaslin Nuna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
