Mount Tricorn
Mount Tricorn () is a distinctive massif whose vertical rock faces rise to 1,120 m and surround a snow-covered interior which is lower except for a 1,610 m peak in the northwest portion, standing at the head of Wright Inlet on the east coast of Palmer Land. Discovered by members of the United States Antarctic Service (USAS) in a flight from East Base East Base on Stonington Island is the oldest American research station in Antarctica, having been commissioned by Franklin D. Roosevelt in 1939. The station was built as part of two US wintering expeditions – United States Antarctic Service Expe ... on December 30, 1940, and named for its resemblance to a gigantic tri-cornered hat.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The 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 prominence or 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. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Wright Inlet
Wright Inlet () is an ice-filled inlet receding westward between Cape Little and Cape Wheeler along the east coast of Palmer Land. The inlet was photographed from the air in 1940 by the United States Antarctic Service (USAS) and in 1947 by the Ronne Antarctic Research Expedition (RARE) under Ronne. Named by Ronne for John K. Wright, Director of the American Geographical Society, which lent its auspices to Ronne's expedition.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deceptio ...

United States Antarctic Service
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 ...

East Base
East Base on Stonington Island is the oldest American research station in Antarctica, having been commissioned by Franklin D. Roosevelt in 1939. The station was built as part of two US wintering expeditions – United States Antarctic Service Expedition (1939–1941) and Ronne Antarctic Research Expedition (1947–1948). The base covers from north to south and from east to west. The base was accorded the status of one of the Historic Sites and Monuments in Antarctica on 7 May 2004. First expedition The Antarctic Service Expedition was the first government-funded expedition of Admiral Richard E. Byrd (his first two expeditions in 1928–1930 and 1933–1935 were privately funded). East Base was built using Army knockdown buildings and a crew of 23 led by Richard Black, after Admiral Byrd had to return to Washington on the USS ''Bear''. The war time pressures and pack-ice in the bay which prevented ship movement led to the evacuation of the base in 1941 by air. Second expeditio ...

Mount Gorham
The Hutton Mountains are a group of mountains in southeastern Palmer Land, Antarctica, bounded on the southwest by Johnston Glacier, on the northwest by Squires Glacier, on the north by Swann Glacier, and on the east by Keller Inlet. The mountains were observed and photographed from the air by the Ronne Antarctic Research Expedition, 1947–48, they were mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–67, and were named by the Advisory Committee on Antarctic Names after James Hutton James Hutton (; 3 June O.S.172614 June 1726 New Style. – 26 March 1797) was a Scottish geologist, agriculturalist, chemical manufacturer, naturalist and physician. Often referred to as the father of modern geology, he played a key role i ..., a Scottish geologist. References Mountain ranges of Palmer Land {{PalmerLand-geo-stub ...
