Gallagher Ridge
Mount Newall () is a peak, high, the northeast extremity of Asgard Range, in Victoria Land, Antarctica. It was discovered by the Discovery Expedition (1901–04) and named for one of the men who helped raise funds to send a relief ship for the expedition. Location Mount Newall is in the northeast of the Asgard Range. It rises over the Newall Glacier to its south, which flows northeast into the Wilson Piedmont Glacier to the east of the mountain. Mount Loke and the eastern end of the Wright Valley are to the northwest of the mountain. The Denton Glacier, Goodspeed Glacier and Hart Glacier (Antarctica), Hart Glacier descend into the Wright Valley from the ridge that extends southwest from the mountain. Features Named features in the region around Mount Newall include: Mount Loke . A horn shaped peak on the south wall of Wright Valley, standing between Goodspeed and Denton Glaciers. Named by the VUWAE, 1958-59, after one of the Norse gods. Decker Glacier . A steep, narrow gla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in 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 78th parallel south, 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 Victoria of the United Kingdom, 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. History Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 Meteorite, meteorites in Antarctica, some of which were found near the Allan Hills in Victoria Land. The meteorites appeared to have undergone little change since they were formed at what scientists believe was the birth of the Solar System. In 1981, Lichen, lichens fo ...

Asgard Range
The Asgard Range () is a mountain range in Victoria Land, Antarctica. It divides Wright Valley from Taylor Glacier and Taylor Valley. It is south of the Olympus Range and north of the Quartermain Mountains and the Kukri Hills. Name The Asgard Range was named by the Victoria University of Wellington Antarctic Expedition (1958–59) after Asgard, the home of the Norse gods. Location The Asgard Range extends in a west–east direction from Wright Upper Glacier, below the Antarctic Plateau, to Mount Newall above the Wilson Piedmont Glacier, which extends along the west coast of the Ross Sea. To the north, the Asgard Range is separated from the Olympus Range by the Wright Upper Glacier and the Wright Valley, from which the Wright Lower Glacier flows into the Wilson Piedmont Glacier. To the south, the Taylor Glacier and Taylor Valley separate the Asgard Range from the Quartermain Mountains and the Kukri Hills. Surrounding major glaciers and valleys * Wright Upper Glacie ...

Discovery Expedition
The ''Discovery'' Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean and William Lashly. Its scientific results covered extensive ground in biology, zoology, geology, meteorology and magnetism. The expedition discovered the existence of the only snow-free Antarctic valleys, which contains the longest river of Antarctica. Further achie ...

Newall Glacier
The Newall Glacier () is a glacier in the east part of the Asgard Range of Victoria Land, It flows east between Mount Newall and Mount Weyant into the Wilson Piedmont Glacier. The Newall Glacier was mapped by the N.Z. Northern Survey Party of the CTAE, 1956-58, who named it after nearby Mount Newall. Location The Newall Glacier forms to the east of the Lacroix Glacier, which flows south into Taylor Valley. It flows northeast, past the head of Suess Glacier, past Mount Valkyrie to the west and Mount Weyant to the east. It turns east and is joined by the Loftus Glacier below Mount Newall. It continues east past the head of Commonwealth Glacier and joins with Wright Lower Glacier as it flows into Wilson Piedmont Glacier. Features Features, from southwest to northeast, include Lyons Cone, Twickler Cone, Unwin Ledge, Hothern Cliffs, Mount Hall, Loftus Glacier, Mount Weyant, Mount Saga, Hetha Peak, Commanda Glacier and Repeater Glacier.

Wilson Piedmont Glacier
Wilson Piedmont Glacier () is a large piedmont glacier extending from Granite Harbour to Marble Point on the coast of Victoria Land. Discovery and name The Wilson Piedmont Glacier was discovered by the ''Discovery'' expedition, 1901–1904. The British Antarctic Expedition, 1910–1913, named the feature for Dr. Edward A. Wilson, surgeon and artist with Scott's first expedition and chief of the scientific staff with the second. Wilson lost his life on the way back from the South Pole with Scott. Glaciology The Wilson Piedmont Glacier extends along the coastal plain of the west coast of the Ross Sea from Granite Harbor south to McMurdo Sound. Most of its input is from direct precipitation, but it receives some inflows from alpine glaciers. It has a broad dome with a divide near the McMurdo Dry Valleys. Most ice flows east to the Ross Sea, where the glacier terminates and comes afloat in the sea along its eastern margin. Some ice flows west and contributes to the Wright Low ...

Wright Valley
The Wright Valley () is a large east–west trending valley, formerly occupied by a glacier but now ice free except for Wright Upper Glacier at its head and Wright Lower Glacier at its mouth, in Victoria Land, Antarctica. It was named by the VUWAE (1958-59) for Sir Charles Wright, for whom the BrAE (1910-13) named the glacier at the mouth of this valley. The Wright Valley is the central one of the three large McMurdo Dry Valleys in the Transantarctic Mountains, located west of McMurdo Sound. Wright Valley contains the Onyx River, the longest river in Antarctica, Lake Brownworth, the origin of the Onyx River, and Lake Vanda, which is fed by the Onyx River. Its southwestern branch, ''South Fork'', is the location of Don Juan Pond. The upland area known as the Labyrinth is at the valley's west end. Exploration Although portions of the interconnected valley system were discovered in 1903 by the ''Discovery'' expedition led by Captain Robert Falcon Scott, the Wright Valle ...
