Four Ramps
The Four Ramps () are a group of four small rock spurs, roughly parallel and projecting through the snow surface, forming the northeast part of Sullivan Ridge on the west side of Ramsey Glacier, Antarctica. They were discovered and photographed by U.S. Navy Operation Highjump (1946–47) and given this descriptive name by the 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.

Sullivan Ridge
Sullivan Ridge () is a massive ridge, 15 nautical miles (28 km) long, displaying a steep, irregular east slope overlooking Ramsey Glacier and a low gradient, ice-covered west slope overlooking Muck Glacier. The ridge extends generally north from Husky Heights and terminates at the confluence of Muck and Ramsey Glaciers. Discovered and photographed by U.S. Navy Operation Highjump (1946–47) and named by Advisory Committee on Antarctic Names (US-ACAN) for Walter S. Sullivan of the New York Times staff, who has written extensively on Antarctic research and exploration.

Ramsey Glacier
Ramsey Glacier () is a glacier about 45 nautical miles (80 km) long, originating in the Bush Mountains near the edge of the polar plateau and flowing north to the Ross Ice Shelf eastward of Den Hartog Peak. Discovered by the United States Antarctic Service (USAS) on Flight C of February 29-March 1, 1940, and named by Advisory Committee on Antarctic Names (US-ACAN), on the recommendation of R. Admiral Byrd, for Admiral DeWitt Clinton Ramsey, U.S. Navy, Vice Chief of Naval Operations during U.S. Navy Operation Highjump, 1946–47.

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 Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridges Of The Ross Dependency
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
