Rambo Nunataks
Rambo Nunataks () is a loose chain of nunataks which lie northwest of Patuxent Range and extend along the west side of the Foundation Ice Stream for 17 nautical miles (31 km) in the Pensacola Mountains. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1956–66. Named by Advisory Committee on Antarctic Names (US-ACAN) for William L. Rambo, geophysicist in the Pensacola Mountains, 1965–66. Features Geographical features include: * Blackburn Nunatak * Kuhn Nunatak * Möller Ice Stream * Oliver Nunatak * Sowle Nunatak * Wagner Nunatak [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Patuxent Range
The Patuxent Range or macizo Armada Argentina is a major range of the Pensacola Mountains, comprising the Thomas Hills, Anderson Hills, Mackin Table and various nunataks and ridges bounded by the Foundation Ice Stream, Academy Glacier and the Patuxent Ice Stream. Discovered and partially photographed on January 13, 1956 in the course of a transcontinental nonstop plane flight by personnel of U.S. Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return. Named by Advisory Committee on Antarctic Names (US-ACAN) for the Naval Air Station Patuxent River (at Cedar Point, Maryland) located on the south side of the mouth of the Patuxent River. The range was mapped in detail by USGS from surveys and U.S. Navy air photos, 1956-66.

Foundation Ice Stream
Foundation Ice Stream is a major ice stream in Antarctica's Pensacola Mountains. The ice stream drains northward for along the west side of the Patuxent Range and the Neptune Range to enter the Ronne Ice Shelf westward of Dufek Massif. The United States Geological Survey mapped the stream from surveys and U.S. Navy air photos, 1956–66. The Advisory Committee on Antarctic Names named the stream in recognition of the National Science Foundation, which provided major support to the U.S. Antarctic Research Program during this period.

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.
