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.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

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.

Browning Pass (Antarctica)
Browning Pass () is an ice-covered pass, long, lying between the main mass of Deep Freeze Range and the Northern Foothills in Victoria Land, Antarctica. The pass facilitates movement between the lower ends of Priestley Glacier and Campbell Glacier. The feature was first mapped as a part of Campbell Glacier by the Northern Party of the British Antarctic Expedition, 1910–13 (BrAE). It was remapped by the Southern Party of the New Zealand Geological Survey Antarctic Expedition, 1962–63, and named for Frank V. Browning, a member of the BrAE Northern Party, for whom nearby Mount Browning is also named.

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. See also * Ice shelves of Antarctica This is a list of Antarctic ice shelves. Ice shelves are attached to a large portion of the Antarctic coastline. Their total area is 1,541,700 km2. Names are also listed in the Scientific Committee on Antarctic Research, Gazetteer. The ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Antarctic Expedition, 1910–13
The ''Terra Nova'' Expedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place between 1910 and 1913. Led by Captain Robert Falcon Scott, the expedition had various scientific and geographical objectives. Scott wished to continue the scientific work that he had begun when leading the ''Discovery'' Expedition from 1901 to 1904, and wanted to be the first to reach the geographic South Pole. He and four companions attained the pole on 17 January 1912, where they found that a Norwegian team led by Roald Amundsen had preceded them by 34 days. Scott's party of five died on the return journey from the pole; some of their bodies, journals, and photographs were found by a search party eight months later. The expedition, named after its supply ship, was a private venture financed by public contributions and a government grant. It had further backing from the Admiralty, which released experienced seamen to the expedition, and from the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boomerang
A boomerang () is a thrown tool, typically constructed with aerofoil sections and designed to spin about an axis perpendicular to the direction of its flight. A returning boomerang is designed to return to the thrower, while a non-returning boomerang is designed as a weapon to be thrown straight and is traditionally used by some Aboriginal Australians for hunting. Historically, boomerangs have been used for hunting, sport, and entertainment and are made in various shapes and sizes to suit different purposes. Although considered an Australian icon, ancient boomerangs have also been discovered in Africa, the Americas, and Eurasia. Description A boomerang is a throwing stick with aerodynamic properties, traditionally made of wood, but also of bone, horn, tusks and even iron. Modern boomerangs used for sport may be made from plywood or plastics such as ABS, polypropylene, phenolic paper, or carbon fibre-reinforced plastics. Boomerangs come in many shapes and sizes dependin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
