Mount Dietz
Mount Dietz () is a mountain in Antarctica, high, just north of the confluence of Souchez Glacier and Bartlett Glacier where it marks the southern limit of the Hays Mountains in the Queen Maud Mountains. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for Lieutenant D.L. Dietz, U.S. Navy, a pilot on photographic flights during Operation Deep Freeze 1964 and 1965. References Mountains of the Ross Dependency Amundsen Coast {{Ross-mountain-stub ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern 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 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 measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Souchez Glacier
The Scott Glacier is a major glacier, long, that drains the East Antarctic Ice Sheet through the Queen Maud Mountains to the Ross Ice Shelf. The Scott Glacier is one of a series of major glaciers flowing across the Transantarctic Mountains, with the Amundsen Glacier to the west and the Leverett and Reedy glaciers to the east. Geography The Scott Glacier originates on the Antarctic Plateau in the vicinity of D'Angelo Bluff and Mount Howe, and descends between the Nilsen Plateau and the mountains of the Watson Escarpment to enter Ross Ice Shelf just west of the Tapley Mountains. The Tapley Mountains, Watson Escarpment, Mount Blackburn, and the La Gorce Mountains bound the Scott Glacier on its eastern margin, while the Karo Hills, Hays Mountains, Faulkner Escarpment, and Rawson Mountains define the western edge of the Scott's drainage. History Scott Glacier was discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould. The Scott Glacie ...

Bartlett Glacier
Bartlett Glacier () is a tributary glacier, about long and wide at its terminus, flowing northeast from Nilsen Plateau and joining Scott Glacier close north of Mount Gardiner. It was discovered in December 1934 by the Byrd Antarctic Expedition geological party under Quin Blackburn, and named by Richard E. Byrd for Captain Robert A. Bartlett of Brigus, Newfoundland, a noted Arctic navigator and explorer who recommended that the expedition acquire the ''Bear'', an ice-ship which was purchased and rechristened by Byrd as the ''Bear of Oakland''.

Hays Mountains
The Hays Mountains () are a large group of mountains and peaks of the Queen Maud Mountains of Antarctica, surmounting the divide between the lower portions of Amundsen Glacier and Scott Glacier and extending from the vicinity of Mount Thorne on the northwest to Mount Dietz on the southeast. They were discovered by Rear Admiral Richard E. Byrd on the South Pole flight of November 28–29, 1929, and mapped in part by the Byrd Antarctic Expedition geological parties to this area in 1929 and 1934. They were named by Byrd for Will H. Hays, former head of the Motion Picture Producers and Distributors of America. Key features Mount Astor, a prominent peak in the range, was named by Byrd for Vincent Astor, of the Astor family, for his philanthropic contributions to the 1929 expedition. Features Geographical features include: * Cappellari Glacier * Cox Peaks * Dragons Lair Névé * Fission Wall * Forbidden Valley * Heinous Peak * Koerwitz Glacier * Mount Armstrong * Mount Astor * M ...

Queen Maud Mountains
The Queen Maud Mountains are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales. Despite the name, they are not located within Queen Maud Land. Elevations bordering the Beardmore Glacier, at the western extremity of these mountains, were observed by the British expeditions led by Ernest Shackleton (1907–09) and Robert Falcon Scott (1910-13), but the mountains as a whole were mapped by several American expeditions led by Richard Evelyn Byrd (1930s and 1940s), and United States Antarctic Program (USARP) and New Zealand Antarctic Research Program (NZARP) expeditions from the 1950s through the 1970s.

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] |
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. (There was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of The Ross Dependency
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
