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.
The Advisory Committee on Antarctic Names is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica.
The Pensacola Mountains are a large group of mountain ranges of the Transantarctic Mountains System, located in the Queen Elizabeth Land region of Antarctica.
The Patuxent Range or macizo Armada Argentina is a major range of the Pensacola Mountains, comprising the Thomas Hills, Anderson Hills, Mackin Table and various nunataks and ridges bounded by the Foundation Ice Stream, Academy Glacier and the Patuxent Ice Stream. Discovered and partially photographed on January 13, 1956 in the course of a transcontinental nonstop plane flight by personnel of U.S. Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return.
The Heritage Range is a major mountain range, 160 km (99 mi) long and 48 km (30 mi) wide, situated southward of Minnesota Glacier and forming the southern half of the Ellsworth Mountains in Antarctica. The range is complex, consisting of scattered ridges and peaks of moderate height, escarpments, hills and nunataks, with the various units of relief set off by numerous intervening glaciers.
Polar Times Glacier is a glacier on Ingrid Christensen Coast, flowing northward between Svarthausen Nunatak and Boyd Nunatak into the western part of Publications Ice Shelf. It was delineated by John H. Roscoe from aerial photographs taken by USN Operation Highjump, 1946–1947, and named by Roscoe after The Polar Times, a polar journal published by the American Polar Society, New York City.
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.
Snow Hill Island is an almost completely snowcapped island, 33 km (21 mi) long and 12 km (7.5 mi) wide, lying off the east coast of the Antarctic Peninsula. It is separated from James Ross Island to the north-east by Admiralty Sound and from Seymour Island to the north by Picnic Passage. It is one of several islands around the peninsula known as Graham Land, which is closer to Argentina and South America than any other part of the Antarctic continent.
Aitkenhead Glacier is a 10-mile (16 km) long glacier flowing east-southeast from the Detroit Plateau, Graham Land, into Prince Gustav Channel. It was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960–61), and named by the United Kingdom Antarctic Place-Names Committee for Neil Aitkenhead, a FIDS geologist at Hope Bay (1959–60).
Kienle Nunataks are three aligned nunataks to the north of Mount Terror in northeastern Ross Island, Antarctica. The nunataks trend east–west for 1 nautical mile (2 km) and rise to about 1,700 metres (5,600 ft). The central nunatak is 2.5 nautical miles (5 km) north-northeast of the Mount Terror summit. At the suggestion of P.R. Kyle, they were named by the Advisory Committee on Antarctic Names after Juergen Kienle of the Geophysical Institute, University of Alaska Fairbanks, a United States Antarctic Program team leader for the investigation of volcanic activity and seismicity on Mount Erebus in six field seasons, 1980–81 through 1985–86.
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.
Wandel Land is a 15.7 km (52,000 ft) nunatak in the Qaasuitsup municipality in northwestern Greenland. It is one of several nunataks in the Melville Bay region of Greenland, where the Greenland ice sheet drains into the bay alongside its entire length apart from an occasional nunatak.
Centipede Nunatak is a narrow nunatak that is 0.3 nautical miles (0.6 km) long, located 0.8 nautical miles (1.5 km) north-northwest of Ford Rock in central Hut Point Peninsula, Ross Island. The name is allusive; snow that cuts across parts of the nunatak gives it a segmented appearance resembling that of a centipede. It was named by the Advisory Committee on Antarctic Names in 2000.
Takahe Nunatak is the northern of two similar nunataks that lie 0.3 nautical miles (0.6 km) apart and 3.3 nautical miles (6 km) north-northeast of Mount Bird in northwest Ross Island. It rises to c.1100 m and, like Kakapo Nunatak is one of several features near Mount Bird assigned the native name of a New Zealand mountain bird. Named by New Zealand Geographic Board (NZGB), 2000.
The Marion Nunataks are a small group of nunataks rising to about 600 m (2,000 ft) on Charcot Island, in the eastern Bellinghausen Sea of Antarctica. They form a 12 km chain of rocky outcrops on the mid-north coast of the island, stretching from Mount Monique at the western end to Mount Martine in the east.
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.
Kakapo Nunatak is the southern of two similar nunataks that lie 0.3 nautical miles (0.6 km) apart and 3.3 nautical miles (6 km) north-northeast of Mount Bird in northwestern Ross Island. It rises to about 1,200 metres (4,000 ft) and, like Takahe Nunatak close northeast, appears to be part of an ice-covered crater rim. Kakapo Nunatak is one of several features near Mount Bird assigned the native name of a New Zealand mountain bird, in this case the kakapo. It was named by the New Zealand Geographic Board in 2000.
The Kea Nunataks are a line of several nunataks 1.2 nautical miles (2.2 km) southeast of the summit of Mount Bird, Ross Island, Antarctica. The feature trends northwest–southeast and is 1.5 nautical miles (3 km) long. This is one of several features near Mount Bird assigned the native name of a New Zealand mountain bird, in this case a kea. It was named by the New Zealand Geographic Board in 2000.
Lerchenfeld Glacier is a glacier flowing in a west-northwesterly direction between Bertrab Nunatak and the Littlewood Nunataks in Antarctica. It coalesces with the southern flank of Schweitzer Glacier before the combined flow discharges into the head of Vahsel Bay. The glacier was discovered by the Second German Antarctic Expedition, 1911–12, under Wilhelm Filchner, who named this feature for Count Hugo von und zu Lerchenfeld-Köfering, a supporter of the expedition.
