Forrestal Range
The Forrestal Range () is a largely snow-covered mountain range, about long, standing east of Dufek Massif and the Neptune Range in the Pensacola Mountains of Antarctica. Discovered and photographed on 13 January 1956 on a transcontinental patrol plane flight of U.S. Navy Operation Deep Freeze I from McMurdo Sound to the vicinity of the Weddell Sea and return. Named by the US-ACAN after , first supercarrier of the U.S. Navy. The entire Pensacola Mountains were mapped by USGS in 1967 and 1968 from U.S. Navy tricamera aerial photographs taken in 1964. Key mountains * Abele Spur () is a rock spur that descends west from Mount Lechner toward the Herring Nunataks. It was named by US-ACAN at the suggestion of Arthur B. Ford for Gunars Abele, civil engineer on the 1973–1974 United States Antarctic Research Program (USARP)-CRREL survey in this area. * Blount Nunatak () is a prominent nunatak, , standing southwest of Mount Lechner on the west side of Forrestal Range.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butler Rocks
The Butler Rocks are two rock nunataks, high, standing southwest of Vanguard Nunatak in the northern Forrestal Range, Pensacola Mountains.

Pensacola Mountains
The Pensacola Mountains are a large group of mountain ranges of the Transantarctic Mountains System, located in the Queen Elizabeth Land region of Antarctica. Geography They extend 450 km (280 mi) in a NE-SW direction. Subranges of the Pensacola Mountains include: Argentina Range, Forrestal Range, Dufek Massif, Cordiner Peaks, Neptune Range, Patuxent Range, Rambo Nunataks and Pecora Escarpment. These mountain units lie astride the extensive Foundation Ice Stream and Support Force Glacier which drain northward to the Ronne Ice Shelf. ;Naming Discovered and photographed on 13 January 1956 in the course of a transcontinental nonstop plane flight by personnel of United States Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return. Named by US-ACAN for the U.S. Naval Air Station, Pensacola, Florida, in commemoration of the historic role of that establishment in training aviators of the U.S. Navy.

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] |

Ellsworth Station
Ellsworth Scientific Station ( es, Estación Científica Ellsworth, or simply ''Estación Ellsworth'' or ''Base Ellsworth'') was a permanent, all year-round originally American, then Argentine Antarctic scientific research station named after American polar explorer Lincoln Ellsworth. It was located on Gould Bay, on the Filchner Ice Shelf. It was shut down in 1962 over safety concerns due to it being built on increasingly unstable ice, which produced fast deterioration of its superstructures and endangered both personnel and equipment. History Ellsworth Station was built by United States Navy Seabees under the command of Captain Finn Ronne, with the support of the icebreakers USS ''Staten Island'' and USS ''Wyandot'', captained by Francis Gambacorta. The originally planned site for the station was Cape Adams, but when the terrain proved impractical due to huge ice cliffs, an alternate location on Gould Bay was selected, on the western coast of the Weddell Sea over the Filchner ...
