Half Dome Nunatak
Half Dome Nunatak () is a nunatak lying south of the Cobham Range in Antarctica, at the mouth of Lucy Glacier. It was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s. Features named by the expeditions 1957 ... (1961–62) because it is rounded on one side and cut into sheer cliffs on the other side.

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] |
Cobham Range
The Cobham Range () is a mountain range in the Churchill Mountains of the Ross Dependency, Antarctica. It extends to the north of the Nimrod Glacier. Location The Cobham Range trends in a northwest–southeast direction for about in the southern part of the Churchill Mountains of the Ross Dependency, Antarctica. The Prince Philip Glacier runs south down the east side of the Cobham Range, and the Lucy Glacier runs southeast down the west side. They both feed the Nimrod Glacier, which flows to the northeast past the south end of the range. The Holyoake Range is east of the Cobham Range on the east side of the Prince Philip Glacier. The Queen Elizabeth Range is south of the Cobham Range on the south side of the Nimrod Glacier. Early exploration and naming The Cobham Range was mapped by the northern party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1961–62, and named by the New Zealand Antarctic Place-Names Committee for a former Governor-General of New ...

Lucy Glacier
The Nimrod Glacier is a major glacier about 135 km (85 mi) long, flowing from the polar plateau in a northerly direction through the Transantarctic Mountains between the Geologists and Miller Ranges, then northeasterly between the Churchill Mountains and Queen Elizabeth Range, and finally spilling into Shackleton Inlet and the Ross Ice Shelf between Capes Wilson and Lyttelton. It was photographed from the air by USN Operation Highjump, 1946–47. The name, given by US-ACAN, is in association with Shackleton Inlet and is for the ''Nimrod'', the ship of the British Antarctic Expedition (1907–09) under Ernest Shackleton Sir Ernest Henry Shackleton (15 February 1874 – 5 January 1922) was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic.
