Mount Dickason
The Deep Freeze Range () is a rugged mountain range, over long and about wide, rising between Priestley Glacier, Priestley and Campbell Glacier, Campbell Glaciers in Victoria Land, Antarctica, and extending from the edge of the polar plateau to Terra Nova Bay. Peaks in the low and mid portions of the range were observed by early British expeditions to the Ross Sea. The range was mapped in detail by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1955-63. It was named by the Advisory Committee on Antarctic Names in recognition of the support to research provided by the U.S. Navy's Operation Deep Freeze expeditions to Antarctica for many years beginning in 1954. __NOTOC__ Geological features Mount Adamson Mount Adamson () is a summit (topography), peak, high, rising east-northeast of Mount Hewson. It was named by the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1965–66, for R. Adamson, a geologist with thi ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boomerang Glacier
Boomerang Glacier () is a gently curving glacier, long, draining southward from Mount Dickason in the Deep Freeze Range to enter Browning Pass (Antarctica), Browning Pass, at the north side of the Nansen Ice Sheet in Victoria Land. It was discovered by the Northern Party of the British Antarctic Expedition, 1910–13, and so named by them because of its boomerang-like shape.

Nansen Ice Sheet
Nansen Ice Sheet (), or Nansen Ice Shelf, is a by ice shelf. It is nourished by the Priestley and Reeves Glaciers and abutting the north side of the Drygalski Ice Tongue, along the coast of Victoria Land, Antarctica. This feature was explored by the South Magnetic Polar Party of the British Antarctic Expedition, 1907-09 and by the Northern Party of the British Antarctic Expedition, 1910-13. Frank Debenham, geologist with the latter expedition, applied the name Nansen Sheet as the feature is adjacent to Mount Nansen, the dominating summit in the area.

Cape Sastrugi
Cape Sastrugi () is a sharply projecting point on the west side of Deep Freeze Range, standing 1.5 nautical miles (2.8 km) northwest of Snowy Point The Deep Freeze Range () is a rugged mountain range, over long and about wide, rising between Priestley and Campbell Glaciers in Victoria Land, Antarctica, and extending from the edge of the polar plateau to Terra Nova Bay. Peaks in the low and ... and overlooking the north portion of Nansen Ice Sheet, in Victoria Land. First explored by the Northern Party of the British Antarctic Expedition, 1910–13, and so named by them because of large and extensive sastrugi that impeded the travel of this party in approaching the point.

McMurdo Station
McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the area ...

Shafer Peak Formation
The Hanson Formation (also known as the Shafer Peak Formation) is a geologic formation on Mount Kirkpatrick and north Victoria Land, Antarctica. It is one of the two major dinosaur-bearing rock groups found on Antarctica to date; the other is the Snow Hill Island Formation and related formations from the Late Cretaceous of the Antarctic Peninsula. The formation has yielded some Mesozoic specimens, but most of it is as yet unexcavated. Part of the Victoria Group of the Transantarctic Mountains, it lies below the Prebble Formation and above the Falla Formation. The formation includes material from volcanic activity linked to the Karoo-Ferar eruptions of the Lower Jurassic. The climate of the zone was similar to that of modern southern Chile, humid, with a temperature interval of 17–18 degrees. The Hanson Formation is correlated with the Section Peak Formation of the Eisenhower Range and Deep Freeze Range, as well as volcanic deposits on the Convoy Range and Ricker Hil ...
