Greenville Valley
Greenville Valley () is the large mainly ice-free valley lying south of Elkhorn Ridge in the Convoy Range of Victoria Land, Antarctica. A lobe of the Northwind Glacier flows a short distance west into the mouth of the valley. Near the head of the valley the south wall is breached by the entrance to Merrell Valley. It was explored in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition, 1956–58, and was named by them after the USNS ''Greenville Victory'', a freighter in the main American convoy into McMurdo Sound McMurdo Sound is a sound in Antarctica.

Elkhorn Ridge
Elkhorn Ridge () is a rugged ridge, long, between Towle Glacier and Northwind Glacier in the Convoy Range of Victoria Land. It was mapped by the United States Geological Survey from ground surveys and Navy air photos, and was named by the Advisory Committee on Antarctic Names in 1964 for the USNS ''Elkhorn'', a tanker in the American convoy into McMurdo Sound McMurdo Sound is a sound in Antarctica.

Convoy Range
Convoy Range () is a broad mountain range in Antarctica. Much of the range has a nearly flat plateau-like summit, extending south from the Fry Saddle and ending at Mackay Glacier. The range has steep cliffs on its east side, but it slopes gently into the Cambridge Glacier on the western side. The New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) worked in this area in 1957. The party named the range for the main convoy into McMurdo Sound in the 1956–57 season, with the names of the various vessels being used for features in the range. Features Taff Y Bryn () is a ridgelike summit capped by dolerite (about 1,600 m), situated 1 nautical mile (1.9 km) west of Flagship Mountain in the Convoy Range. It is named after the River Taff in Wales, the toponym in Welsh literally means "Hill of the Taff." It was named by the 1976–77 Victoria University of Wellington Antarctic Expedition (VUWAE) led by Christopher J. Burgess. Othe ...

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] |
Northwind Glacier
Northwind Glacier () is a large Antarctic glacier; one of the major sources of the Fry Glacier, in the Convoy Range, Victoria Land. The glacier drains the west part of Flight Deck Neve and flows north between Elkhorn Ridge and Sunker Nunataks to Fry Glacier. A lobe of the glacier flows west a short distance into the mouth of Greenville Valley. Named by the New Zealand Northern Survey Party (1956–57) of the Commonwealth Trans-Antarctic Expedition after the USCGC ''Northwind'' (WAGB-282), an icebreaker in the main American convoy into McMurdo Sound during Operation Deep Freeze Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on.

Merrell Valley
Merrell Valley is a valley in the Convoy Range of Antarctica. It is officially described as: A long, narrow ice-free valley in the Convoy Range, running north from its head immediately east of Mount Gunn into the Greenville Valley. Mapped in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole.

Commonwealth Trans-Antarctic Expedition
The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and 1912. In keeping with the tradition of polar expeditions of the Heroic Age of Antarctic Exploration, the CTAE was a private venture, though it was supported by the governments of the United Kingdom, New Zealand, United States, Australia and South Africa, as well as many corporate and individual donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. The New Zealand party included scientists participating in International Geophysical Year research while the British team were separately based at Halley Ba ...

USNS Greenville Victory (T-AK-237)
SS ''Greenville Victory'' was a cargo Victory ship built in 1944, during World War II under the Emergency Shipbuilding program. The ship’s United States Maritime Commission designation was VC2-S-AP3, hull number 18 (V-18). Post-war she was acquired by the U.S. Army and renamed as USAT ''Greenville Victory''. She was acquired by the U.S. Navy in 1950, renamed USNS ''Greenville Victory'' (T-AK-237) and assigned to the Military Sea Transportation Service (MSTS) who operated her safely through the Korean War and Vietnam War campaigns. She was the lead ship in her class of 9 ships that were transferred to the MSTS in 1950. She returned home with two battle stars to her credit and was struck in 1987. Victory built in California ''Greenville Victory'' was laid down under U.S. Maritime Commission contract by California Shipbuilding Corporation, Los Angeles, California; 21 March 1944; launched 28 May 1944; sponsored by Miss Mary J. Vukov; and delivered to the War Shipping Administra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McMurdo Sound
McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo of HMS ''Terror''. The sound today serves as a resupply route for cargo ships and for airplanes that land on the floating ice airstrips near McMurdo Station. Physical characteristics Wildlife in the sound include killer whales, seals, Adélie penguins, and emperor penguins. Boundary and Extents The sound extends approximately 55 kilometers (34 mi) in length and width, and opens into the larger Ross Sea to the north. To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the McMurdo Ice Shelf (itself part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound, and is the s ...

Valleys Of Victoria Land
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. For ...
