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 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 Sastrugi, or zastrugi, are features formed by erosion of snow by wind. They are found in polar regions, and in snowy, wind-swept areas of temperate regions, such as frozen lakes or mountain ridges. Sastrugi are distinguished by upwind-facing poi ... that impeded the travel of this party in approaching the point. Headlands of Victoria Land Scott Coast {{ScottCoast-geo-stub ...

Deep Freeze Range
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 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 peak, high, rising east-northeast of Mount Hewson.

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.

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] |
Terra Nova Expedition
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] |

Sastrugi
Sastrugi, or zastrugi, are features formed by erosion of snow by wind. They are found in polar regions, and in snowy, wind-swept areas of temperate regions, such as frozen lakes or mountain ridges. Sastrugi are distinguished by upwind-facing points, resembling anvils, which move downwind as the surface erodes. These points usually lie along ridges perpendicular to the prevailing wind; they are steep on the windward side and sloping to the leeward side. Smaller irregularities of this type are known as ripples (small, ~10 mm high) or wind ridges. Large sastrugi are troublesome to skiers and snowboarders. Traveling on the irregular surface of sastrugi can be very tiring, and can risk breaking equipment—ripples and waves are often undercut and the surface is hard and unforgiving, with constant minor topographic changes between ridge and trough. Etymology The words ''sastrugi'' and ''zastrugi'' are Russian-language plurals; the singular is ''zastruga''. The form ''sastrug ...

Headlands Of Victoria Land
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
