Columbia Mountains (Antarctica)
The Columbia Mountains are a group of largely bare rock peaks, ridges and nunataks located near the east margin of the Dyer Plateau, south-east of the Eternity Range, in Palmer Land. They were mapped by the U.S. Geological Survey in 1974, and named by the Advisory Committee on Antarctic Names after Columbia University, New York City, which for several seasons in the 1960s and 1970s sent geologists to study the structure of the Scotia Ridge. Peaks Mount Brocoum is the dominant peak on the eastern ridge of the Columbia Mountains. References * Mountain ranges of Palmer Land {{PalmerLand-geo-stub ...

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. They were mapped by the United States Geological Survey in 1974, and were named ..., a cluster of snow-covered hills th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

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] |
Columbia University
Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States. It is one of nine colonial colleges founded prior to the Declaration of Independence. It is a member of the Ivy League. Columbia is ranked among the top universities in the world. Columbia was established by royal charter under George II of Great Britain. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University. Columbia scientists and scholars have ...

Scotia Ridge
The Scotia Arc is the island arc system forming the north, east and south border of the Scotia Sea. The northern border, the North Scotia Ridge, comprises (from west to east) Isla de los Estados at the tip of Tierra del Fuego, the Burdwood, Davis, and Aurora Banks; the Shag, South Georgia Island and Clerke Rocks. The eastern border comprises the volcanic South Sandwich Islands flanked by the South Sandwich Trench. The southern border, the South Scotia Ridge, (east to west) comprises Herdman, Discovery, Bruce, Pirie, and Jane Banks; the South Orkney Islands and Elephant Island. The Bransfield Strait, finally, separates the arc from the South Shetland Islands and James Ross Island flanking the tip of the Antarctic Peninsula. The Scotia Arc surrounds the small Scotia and South Sandwich Plates. The arc is formed by continental fragments that once formed a land bridge between South America and Antarctica, once part of the subduction margin that still forms the Andes. An ancestral ...
