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.

Towle Glacier
Towle Glacier () is a glacier in the Convoy Range of Victoria Land, draining northeast between Eastwind and Elkhorn Ridges into the Fry Glacier. It was first mapped in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) and named for the USNS Private John R. Towle, an American freighter which carried a large proportion of the New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean.

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.

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 ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

USS Elkhorn (AOG-7)
USS ''Elkhorn'' (AOG-7) was a in service with the U.S. Navy from 1944 to 1972. She was then sold to Taiwan, where she served as ROCS ''Hsing Lung'' (AOG-515/AOG-517). Her final fate is unknown. History United States Navy (1944-1972) ''Elkhorn'' was launched 15 May 1943 by Cargill Inc., Savage, Minnesota; sponsored by Mrs. J. A. Flynn; and commissioned 12 February 1944. World War II ''Elkhorn'' sailed from New Orleans, Louisiana, 25 February 1944 for the South Pacific Ocean, and arrived at Milne Bay, New Guinea, 29 May for duty as station tanker. She made several voyages to Manus to reload and fueled ships in the invasion of Morotai in September 1944, otherwise serving at Milne Bay until March 1945 when she arrived at Leyte. ''Elkhorn'' served throughout the Philippines until 1 December, then returned to the U.S.West Coast for overhaul.

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 ...

Ridges Of Victoria Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
