Lenfant Bluff
Lenfant Bluff () is a rock bluff marking the south side of the mouth of Svendsen Glacier, in the Usarp Mountains of Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–62, and was named by the Advisory Committee on Antarctic Names for Claude J.M. Lenfant, a United States Antarctic Research Program biologist at McMurdo Station McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica.

Svendsen Glacier
Svendsen Glacier () is a meandering glacier, 13 nautical miles (24 km) long, in the Usarp Mountains. It flows northeastward from Mount Marzolf and emerges between McCain Bluff and Lenfant Bluff onto an ice piedmont just west of the terminus of Rennick Glacier. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–62. Named by Advisory Committee on Antarctic Names (US-ACAN) for Kendall L. Svendsen, United States Antarctic Research Program (USARP) geomagnetist at McMurdo Station, 1967–68. Glaciers of Pennell Coast {{PennellCoast-glacier-stub ...

Usarp Mountains
The Usarp Mountains are a major Antarctic mountain range, lying west of the Rennick Glacier and trending north to south for about . The feature is bounded to the north by Pryor Glacier and the Wilson Hills. These mountains were discovered and first photographed from aircraft of the U.S. Navy Operation Highjump in 1946. They were first sighted and entered by the U.S. Victoria Land Traverse 1959-1960 (VLT), and the first ascent of Mount Welcome was made by John G. Weihaupt, Alfred Stuart, Claude Lorius, and Arnold Heine of that traverse team. The mountains were completely mapped by the United States Geological Survey from VLT reports, U.S. Navy air photos from 1960–63, and subsequent surveys. The name is an acronym of the United States Antarctic Research Program (USARP), and was applied by Advisory Committee on Antarctic Names (US-ACAN) in recognition of the accomplishments of that program in Antarctica.

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] |

United States Antarctic Research Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

McMurdo Station
McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base. History The station takes its name from its geographic location on McMurdo Sound, named after Lieutenant Archibald McMurdo of . The ''Terror'', commanded by Irish explorer Francis Crozier, along with expedition flagship ''Erebus'' under command of James Clark Ross, first charted the a ...

Cliffs Of Victoria Land
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also feat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
