A nunatak 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.
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 US-ACAN and UK-APC, 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 degrees south.
The Usarp Mountains is a major Antarctic mountain range, lying westward of the Rennick Glacier and trending N-S for about 190 kilometres (118 mi). The feature is bounded to the north by Pryor Glacier and the Wilson Hills. Its important constituent parts include Welcome Mountain, Mount Van der Hoeven, Mount Weihaupt, Mount Stuart, Mount Lorius, Smith Bench, Mount Roberts, Pomerantz Tableland, Daniels Range, Emlen Peaks, Helliwell Hills and Morozumi Range.
The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies. Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains together with other scattered peaks form an arc about 260 miles long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.
The Scott Mountains are a large number of isolated peaks lying south of Amundsen Bay in Enderby Land of East Antarctica, Antarctica. Discovered on 13 January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson. He named the feature Scott Range after Captain Robert Falcon Scott, Royal Navy. The term mountains is considered more appropriate because of the isolation of its individual features.
Astraea Nunatak is a nunatak 6 miles (10 km) south of Staccato Peaks in southern Alexander Island. It was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50, and named by the United Kingdom Antarctic Place-Names Committee after Astraea, one of the asteroids lying between the orbits of Mars and Jupiter.
Ahlmann Ridge, also known as Ahlmannryggen, is a broad, mainly ice-covered ridge, about 110 km (70 mi) long, surmounted by scattered, low peaks. It rises between Schytt Glacier and Jutulstraumen Glacier and extends from Borg Massif northward to Fimbul Ice Shelf in Queen Maud Land. The area was first photographed from aircraft of the Third German Antarctic Expedition (1938–39) and peaks in this vicinity were roughly plotted. The Stein Nunataks and Witte Peaks, named by the German Antarctic Expedition, appear to coincide with the northeast part of the Ahlmann Ridge. The feature was mapped in detail from surveys and air photos by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–1952) and air photos by the Norwegian expedition (1958–59). Named for Hans Wilhelmsson Ahlmann, chairman of the Swedish committee for the NBSAE.
The Porthos Range is the second range south in the Prince Charles Mountains, extending for about 30 miles in an east-to-west direction between Scylla Glacier and Charybdis Glacier. First visited in December 1956 by the ANARE southern party under W.G. Bewsher and named after Porthos, a character in Alexandre Dumas, père's novel The Three Musketeers, the most popular book read on the southern journey.
Outpost Nunataks are three aligned nunataks standing 4 nautical miles (7 km) southwest of Brimstone Peak in the Prince Albert Mountains, Victoria Land. Mapped by the Southern Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1962–63, and presumably named by the party because of the position of the nunataks near the edge of the polar plateau.
Whistler Nunatak is a nunatak lying west of Mount Mende in the Sky-Hi Nunataks, Palmer Land. Named in 1987 by Advisory Committee on Antarctic Names (US-ACAN) in reference to the whistler effect caused by amplitude change of radio signals in the upper atmosphere and in association with names of upper atmosphere researchers grouped in the area.
Mount Cox is a mountain 1,960 metres (6,430 ft) high in the north-central part of the Emlen Peaks, 5 nautical miles (9 km) north of Killer Nunatak, Victoria Land, Antarctica. The topographical feature was first mapped by the United States Geological Survey (USGS) from surveys and from U.S. Navy air photos, 1960–63, and named by the Advisory Committee on Antarctic Names for Allen N. Cox, U.S. Navy, crew chief in R4D (Skytrain) aircraft during 1962–63 in support of the USGS Topo East-West survey. Cox returned to the Antarctic in the 1963–64 and 1964–65 seasons. The mountain lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Dodd Nunatak is a nunatak 2.5 nautical miles (5 km) west of Mount Cox in the northwest portion of the Emlen Peaks in the Usarp Mountains, a major mountain range within Victoria Land, Antarctica. The geographical feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–63, and was named by the Advisory Committee on Antarctic Names for Walter H. Dodd of the Public Information Office, National Science Foundation, who worked at McMurdo Station, Hut Point Peninsula, Ross Island, in the 1966–67 and 1967–68 austral summer months. The nunatak lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
The Du Toit Nunataks are a group of nunataks between Cornwall Glacier and Glen Glacier, marking the western end of the Read Mountains, Shackleton Range. They were photographed from the air by the U.S. Navy, 1967, and surveyed by the British Antarctic Survey, 1968–71. In association with the names of geologists grouped in this area, they were named by the UK Antarctic Place-Names Committee after Alexander Logie du Toit, a South African geologist.
Lokey Peak is a small, sharp peak, or nunatak, standing at the southeastern extremity of the Guthridge Nunataks, in the Gutenko Mountains of central Palmer Land, Antarctica. It was mapped by the United States Geological Survey in 1974, and was named by the Advisory Committee on Antarctic Names for William M. Lokey, Station Manager at Palmer Station, 1975. He had previously wintered at McMurdo Station in 1970 and 1974.
Huns Nunatak is a nunatak rising to about 950 metres (3,120 ft) in the center of the Milky Way, a mountain pass between the LeMay Range and the Planet Heights, in the central portion of Alexander Island, Antarctica. The name originates from dog teams named "The Huns" that served at various British stations in Antarctica, 1961–74, and honors the loyal service of all Falkland Islands Dependencies Survey/British Antarctic Survey sled dogs. Huns Nunatak seems to bear some relation to Admirals Nunatak, which lies about 6 kilometres (3.7 mi) to the southwest, considering they are both named after a team of sled dogs.
Static Nunatak is a nunatak 2 nautical miles (3.7 km) south-southwest of Altar Mountain, Quartermain Mountains, in Victoria Land. The name is one of a group in the area associated with surveying applied in 1993 by New Zealand Geographic Board (NZGB). Static is a modern survey technique involving stationary observations of survey stations with particular relevance to Global Positioning System (GPS) surveys.
Mount Hemmingsen is a mountain at the northeast end of the Werner Mountains, located on the south side of Meinardus Glacier, 5 nautical miles (9 km) southwest of Court Nunatak, in Palmer Land, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–67, and was named by the Advisory Committee on Antarctic Names for Edvard A. Hemmingsen, a biologist at McMurdo Station in the summer of 1966–67, and at Palmer Station, 1967–68.
Horseshoe Nunatak is a horseshoe-shaped nunatak in the Churchill Mountains of Antarctica, located 5 nautical miles (9 km) west of Mount Hoskins on the north side of the upper portion of Starshot Glacier. The nunatak was charted and descriptively named by the New Zealand Geological Survey Antarctic Expedition of 1964–65.
Kaka Nunatak is the most prominent of the Kea Nunataks, rising to about 1,400 metres (4,600 ft) near the center of the group. It stands 2 nautical miles (4 km) southeast of the summit of Mount Bird in northwestern Ross Island. Kaka Nunatak is one of several features near Mount Bird assigned the name of a New Zealand mountain bird, in this case the "kaka". It was named by the New Zealand Geographic Board in 2000.
