Enterprise Hills

Last updated

The Enterprise Hills are a prominent group of largely ice-free hills and peaks in the form of an arc. The feature extends for about 30 nautical miles (60 km) to form the north and northeast boundary of Horseshoe Valley in the Heritage Range of the Ellsworth Mountains. These hills were mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–66; the name was applied by the Advisory Committee on Antarctic Names in association with the name Heritage Range.

Horseshoe Valley (Antarctica) valley in Antarctica

Horseshoe Valley is a large ice-filled valley in the southern Heritage Range of the Ellsworth Mountains of Antarctica. It is outlined by the semicircular arrangement of the Independence, Marble, Liberty and Enterprise Hills. Approval of the descriptive name was suggested by the University of Minnesota Ellsworth Mountains Party, 1962–63, who reported the name was in wide use by U.S. Navy flyers in the area.

Heritage Range mountain range

The Heritage Range is a major mountain range, 160 km (99 mi) long and 48 km (30 mi) wide, situated southward of Minnesota Glacier and forming the southern half of the Ellsworth Mountains in Antarctica. The range is complex, consisting of scattered ridges and peaks of moderate height, escarpments, hills and nunataks, with the various units of relief set off by numerous intervening glaciers.

Ellsworth Mountains highest mountain ranges in Antarctica

The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a 360 km (224 mi) long and 48 km (30 mi) wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson (4,892 m) constituting the highest point on the continent. Geologically, they are part of the Antarctandes which stretch from the Antarctic Peninsula to Cape Adare on the western shore of the Ross Sea. The Antarctandes form the southernmost arc of the Pacific 'Ring of Fire'. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
