Giannini Peak
Welch Mountains () is a group of Antarctic mountains that dominate the area, the highest peak rising to 3,015 m, located 25 nautical miles (46 km) north of Mount Jackson on the east margin of the Dyer Plateau of Palmer Land. These mountains were probably seen from the air by Ellsworth in 1935 and their north extremities were sketched in 1936 by a British Graham Land Expedition (BGLE) sledge party under Rymill. In 1940 they were photographed from the air and charted from the ground by the United States Antarctic Service (USAS), and in the expedition reports and charts were assumed to be Ellsworth's Eternity Range. The mountains were mapped in detail by United States Geological Survey (USGS) in 1974. Named by Advisory Committee on Antarctic Names (US-ACAN) for Rear Admiral David F. Welch, Commander, U.S. Naval Support Force, Antarctica, 1969–71. See also *Mount Schimansky Mount Schimansky () is a ridge-like mountain 6 nautical miles (11 km) northwest of ...

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Mount Jackson (Antarctica)
Mount Jackson (Mount Andrew Jackson and Mount Ernest Gruening) is a mountain that dominates the upland of the southern part of the Antarctic Peninsula. It is located in Palmer Land, within the Antarctic claims of Argentina, Chile and the United Kingdom. With an elevation of , Mount Jackson was once thought to be the highest mountain in the Antarctic Peninsula and the British Antarctic Territory, before the true height of Mount Hope (Eternity Range) was measured. Discovered by members of the United States Antarctic Service, 1939–41, it was named for Andrew Jackson, the seventh President of the United States. The first ascent of Mount Jackson was made by a team led by John Crabbe Cunningham of the British Antarctic Survey (BAS) in 1964. Mount Jackson's geology was studied in 1972 as part of the Palmer Island investigations by a team of geologists. Mount Jackson and the Welch Mountains demarcate the central Black Coast, which is dissected by many inlets and is bounded on t ...

Dyer Plateau
Dyer Plateau () is a broad ice-covered upland of north-central Palmer Land, bounded to the north by Fleming Glacier and Bingham Glacier, and to the south by the Gutenko Mountains. It is buttressed by Goettel Escarpment. The plateau was first explored on land and photographed from the air by the US Antarctic Service (USAS), 1939–41. It was named after J. Glenn Dyer, a surveyor with the then General Land Office, Department of the Interior. He was leader of the USAS surface party which sledged from Fleming Glacier southeast across the plateau to the Welch Mountains, and U.S. observer with the Australian National Antarctic Research Expeditions during the 1956–57 season. See also *Laine Hills The Laine Hills () are a cluster of four mainly snow-covered hills that rise above the Dyer Plateau about northwest of the Welch Mountains, in Palmer Land, Antarctica.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deceptio ...

United States Antarctic Service
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Eternity Range
The Eternity Range is a range of mountains long, rising to , and trending north–south approximately in the middle of the Antarctic Peninsula, in the Palmer Land region of Antarctica. Geography The Eternity Range is divided into three main mountain blocks, the major summits in each from north to south being Mount Faith, Mount Hope, and Mount Charity. These four names were applied by Lincoln Ellsworth who discovered the range from the air during his flights of November 21 and November 23, 1935. Expeditions In November 1936, the range was surveyed by John Riddoch Rymill of the British Graham Land Expedition who gave the name "Mount Wakefield" to the central mountain in the range. This complication by Rymill, and uncertainty as to the precise location or extent of Ellsworth's discovery, hindered for a time a resolution of its nomenclature (i.e., following the U.S. Antarctic Service expedition in 1939–41, the name Eternity Range or Eternity Mountains was incorrectly applied to ...

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] |
