Argentina Range
The Argentina Range is a mountain range of rock peaks and bluffs, long, lying east of the northern part of Forrestal Range in the northeastern portion of the Pensacola Mountains of Antarctica. Discovered and photographed on January 13, 1956, in the course of a US Navy transcontinental nonstop plane flight from McMurdo Sound to Weddell Sea and return. Named by the Advisory Committee on Antarctic Names after Argentina, which for many years from 1955 maintained a scientific station on the Filchner Ice Shelf at the General Belgrano or Ellsworth Station site. The entire Pensacola Mountains were mapped by United States Geological Survey in 1967 and 1968 from ground surveys and from US Navy tricameral photographs taken in 1964.

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whichaway Nunataks
Whichaway Nunataks () is a group of rocky nunataks extending for 7 nautical miles (13 km) and marking the south side of the mouth of Recovery Glacier. First seen from the air and visited in 1957 by the Commonwealth Trans-Antarctic Expedition and so named because it was uncertain which route from the nunataks would lead furthest inland. The Blackwall Ice Stream joins Recovery Glacier between the Argentina Range The Argentina Range is a mountain range of rock peaks and bluffs, long, lying east of the northern part of Forrestal Range in the northeastern portion of the Pensacola Mountains of Antarctica.

Recovery Glacier
The Recovery Glacier () is a glacier flowing west along the southern side of the Shackleton Range in Antarctica. First seen from the air and examined from the ground by the Commonwealth Trans-Antarctic Expedition in 1957, it was so named because of the recovery of the expedition's vehicles which repeatedly broke into bridged crevasses on this glacier during the early stages of the crossing of Antarctica. It is at least 100 km (60 mi) long and 64 km (40 mi) wide at its mouth. Dana Floricioiu and Irena Hajnsek of the German Aerospace Centre spoke on the radar data showing the interior of the Recovery Glacier at the IEEE Geoscience and Remote Sensing Symposium in Cape Town, South Africa, in July 2009. The data comes from the German public-private satellite Terrasar-X and when combined with Radarsat-1 shows the changes in the glacier over 11 years. The Recovery Ice Stream that drains part of the East Antarctic Ice Sheet into the glacier is nearly long and feeds ... [...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 ...
