Mount Blackwelder
Mount Blackwelder () is a sharp, mainly ice-free peak in north Wilkniss Mountains, Victoria Land, rising to 2,340 m west of Vernier Valley and 10 km (6 mi) north of Pivot Peak. Mapped by USGS from surveys and U.S. Navy aerial photographs, 1947–59. Named by US-ACAN in 1984 after Lieutenant Commander Billy G.

Mountain
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 ...

Wilkniss Mountains
Wilkniss Mountains () is a prominent group of conical mountains, long running north–south, located east-southeast of Mount Feather, Quartermain Mountains, in Victoria Land, Antarctica. The mountains are wide in the north portion where Mount Blackwelder (2,340 m) and Pivot Peak (2,450 m) rise above ice-free valleys. Except for an outlying southwest peak, the south portion narrows to a series of mainly ice-covered smaller peaks. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1992 after Peter E. Wilkniss, a chemist who from 1975 has served in various positions at the National Science Foundation, including Deputy Assistant Director of the Directorate for Scientific, Technological, and International Affairs; Director, Division of Polar Programs, 1984–93; senior science associate to the assistant director for Geosciences, from 1993.

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 A meteorite is a solid piece of debris from an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pivot Peak
Pivot Peak () is a prominent conical peak, 2,470 m, distinguished by a large northeast cirque and as the highest point in Wilkniss Mountains, Victoria Land. 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.

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 hundredth an ...

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 Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctic Development Squadron Six
Antarctic Development Squadron Six (VXE-6 or ANTARCTIC DEVRON SIX, commonly referred to by its nickname, The Puckered Penguins) was a United States Navy air test and evaluation squadron based at Naval Air Station Point Mugu, California with forward operating bases at Christchurch, New Zealand and McMurdo Station, Antarctica. Established at Naval Air Station Patuxent River, Maryland on 17 January 1955 as Air Development Squadron Six (VX-6), the squadron's mission was to conduct operations in support of Operation Deep Freeze, the operational component of the United States Antarctic Program. The squadron relocated to Naval Air Station Quonset Point, Rhode Island on 1 February 1956. On 1 January 1969 the squadron was redesignated Antarctic Development Squadron Six (VXE-6). Following the closure of NAS Quonset Point in the 1970s, the squadron relocated to NAS Point Mugu. Using the tail codes ''XD'' (1955) and ''JD'' (1957), the squadron flew numerous aircraft over the course of it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Deepfreeze
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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
