Whistler Nunatak () is a nunatak lying west of Mount Mende in the Sky-Hi Nunataks, Palmer Land.

Nunatak
A nunatak (from Inuit ''nunataq'') 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 are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude 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 nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Mende
Mount Mende () is a nunatak southwest of Mount Lanzerotti, rising to about in the Sky-Hi Nunataks of Ellsworth Land, Antarctica. It was named by the Advisory Committee on Antarctic Names in 1987 after Stephen B. Mende of the Lockheed Research Laboratory, Palo Alto, California, a Principal Investigator in upper atmosphere research, including auroral studies, carried out at Siple Station and South Pole Station South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz ... from 1973 onwards. References Mountains of Palmer Land {{PalmerLand-geo-stub ...

Sky-Hi Nunataks
Sky-Hi Nunataks is a nunatak group 8 nautical miles (15 km) long, located 11 nautical miles (20 km) east of Grossman Nunataks and northeast of Merrick Mountains in Palmer Land, extending from Doppler Nunatak in the west to Arnoldy Nunatak in the east and including Mount Mende, Mount Lanzerotti, Mount Carrara, and Mount Cahill. History The nunataks were first seen and photographed from the air by Ronne Antarctic Research Expedition (RARE), 1947–48. The name derives from the United States Antarctic Research Program (USARP) project Sky-Hi, in which Camp Sky-Hi (later designated Eights Station) was set up in Ellsworth Land in November 1961 as a conjugate point station to carry on simultaneous measurements of the earth's magnetic field and of the ionosphere. Sky-Hi's conjugate point in the Northern Hemisphere is located in the Réserve faunique des Laurentides, in Canada. The nunataks were mapped in detail by United States Geological Survey (USGS) from ground survey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
