Marze Peak
Marze Peak is a rock peak with twin summits near the south end of the ridge between Wessbecher Glacier and Hudman Glacier, in the Petvar Heights at the south end of the Sentinel Range, Ellsworth Mountains, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos from 1957 to 1959, and was named by the Advisory Committee on Antarctic Names for Marion O. Marze, an aviation machinist's mate from the U.S. Navy who perished in the crash of a P2V Neptune airplane at McMurdo Sound on October 18, 1956.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topography, topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some Topographic prominence, prominence or Topographic isolation, isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent ...

Wessbecher Glacier
Wessbecher Glacier () is a glacier about 7 nautical miles (13 km) long, draining southeast from Mount Inderbitzen and south from Mount Mullen between Peristera Peak, Lishness Peak and Stikal Peak on the main ridge of Sentinel Range on the west and Marze Peak in Petvar Heights on the east, in the Ellsworth Mountains, Antarctica. The glacier was first mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1957–59. It was named by Advisory Committee on Antarctic Names (US-ACAN) for Howard O. Wessbecher, a member of the winter party at McMurdo Sound, 1956, who was representative (assisting in logistical preparations) for the establishing of the South Pole Station.

Hudman Glacier
Hudman Glacier () is a glacier draining south of Mount Landolt between Marze Peak and Miller Peak in Petvar Heights at the south end of the Sentinel Range, in the Ellsworth Mountains of Antarctica, flowing south-southeast to Minnesota Glacier. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Captain Rayburn A. Hudman, United States Marine Corps, who died in the crash of a Lockheed P2V-2n Neptune, modified for extreme range, flying in sub zero temperatures and Ski equipped for landing on the Ice runways at McMurdo Sound Antarctica on 18 October 1956.

Sentinel Range
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about and is wide. Many peaks rise over and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.Sentinel Range.

Ellsworth Mountains
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a long and wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson () constituting the highest point on the continent.Bockheim, J.G., Schaefer, C.E., 2015. ''Soils of Ellsworth Land, the Ellsworth Mountains''. In: Bockheim, J.G. (Ed.), ''The Soils of Antarctica. World Soils Book Series'', Springer, Switzerland, pp. 169–181. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones. Discovery The mountains were discovered on November 23, 1935, by the American explorer Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to the Ross Ice Shelf.

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 ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

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] |
P2V Neptune
The Lockheed P-2 Neptune (designated P2V by the United States Navy prior to September 1962) is a Maritime patrol aircraft, maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed Corporation, Lockheed to replace the Lockheed Ventura, Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion. Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched (using JATO assist), stop-gap nuclear bombers that would have to land on shore or ditch. The type was successful in export, and saw service with several armed forces. Design and development Development of a new land-based patrol bomber began early in World War II, with design work starting at Lockheed's Vega Aircraft Corporation, Vega subsidiary as a private venture on 6 December 1941.Scutts ''Air International'' January 1995, pp. 42–43. At first, the new design was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
