The Ohio Range is a mountain range in the Transantarctic Mountains of Antarctica. It is about 48 km (30 mi) long and 16 km (10 mi) wide, extending WSW-ENE from Eldridge Peak to Mirsky Ledge. The range forms the northeast end of the Horlick Mountains and consists primarily of a large snow-topped plateau with steep northern cliffs and several flat-topped ridges and mountains. The highest point is the summit of Mount Schopf.
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.
The Dater Glacier is a steep valley glacier in Antarctica, 24 nautical miles long and from 1 to 3 nautical miles wide, flowing northeast in a sinuous course from the eastern slopes of the Vinson Massif between Sullivan Heights and Veregava Ridge to Rutford Ice Stream which borders the eastern flank of the Sentinel Range, Ellsworth Mountains. At the lower end the Dater Glacier coalesces with the terminus of the Ellen Glacier, the two emerging from the Sentinel Range as one stream just north of the Flowers Hills.
The Ellen Glacier is a glacier in the central Sentinel Range of the Ellsworth Mountains of Antarctica. It drains the eastern slopes of Mount Anderson and Long Gables and flows generally southeast for 22 nautical miles to Barnes Ridge, where it leaves the range and enters the south flowing Rutford Ice Stream.
Whillans Ice Stream is a glaciological feature of the West Antarctic Ice Sheet, formerly known as Ice Stream B, renamed in 2001 in honor of Ohio State University glaciologist Ian Whillans.
Shabtaie Ice Ridge is an ice ridge between MacAyeal Ice Stream and Bindschadler Ice Stream at the junction of Shirase Coast and Siple Coast, Marie Byrd Land. Named by Advisory Committee on Antarctic Names (US-ACAN) after Sion Shabtaie, Geophysical and Polar Research Center, University of Wisconsin, Madison, WI, who, with Charles R. Bentley, 1982–84 and 1985–86, made a glaciogeophysical survey of the nearby Mercer, Whillans and Kamb Ice Streams and the intervening ice ridges.
Engelhardt Ice Ridge is an ice ridge between Whillans Ice Stream and Kamb Ice Stream near the junction of Gould Coast and Siple Coast in Marie Byrd Land, Antarctica. It was named by the Advisory Committee on Antarctic Names after Hermann Engelhardt of the Division of Geological and Planetary Sciences, California Institute of Technology; he was a United States Antarctic Program geophysicist who drilled boreholes in Whillans and Kamb Ice Streams in four field seasons, 1991–96.
Ahlmann Ridge, also known as Ahlmannryggen, is a broad, mainly ice-covered ridge, about 110 km (70 mi) long, surmounted by scattered, low peaks. It rises between Schytt Glacier and Jutulstraumen Glacier and extends from Borg Massif northward to Fimbul Ice Shelf in Queen Maud Land. The area was first photographed from aircraft of the Third German Antarctic Expedition (1938–39) and peaks in this vicinity were roughly plotted. The Stein Nunataks and Witte Peaks, named by the German Antarctic Expedition, appear to coincide with the northeast part of the Ahlmann Ridge. The feature was mapped in detail from surveys and air photos by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–1952) and air photos by the Norwegian expedition (1958–59). Named for Hans Wilhelmsson Ahlmann, chairman of the Swedish committee for the NBSAE.
Bindschadler Ice Stream is an ice stream between Siple Dome and MacAyeal Ice Stream. It is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983 to 1984 and named Ice Stream A, B, C, etc., according to their position from south to north.
The Echelmeyer Ice Stream, formerly known as Ice Stream F, is a glaciological feature of the West Antarctic Ice Sheet. It is an ice stream flowing west to the Shirase Coast to the north of the MacAyeal Ice Stream, and is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983–84 and originally named Ice Stream A, B, C, etc., according to their position from south to north.
MacAyeal Ice Stream, formerly Ice Stream E, is an ice stream in Antarctica flowing west to the juncture of Shirase Coast and Siple Coast between Bindschadler Ice Stream and Echelmeyer Ice Stream. It is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983–84 onwards and named Ice Stream A, B, C, etc., according to their position from south to north. The name was changed from Ice Stream E by the Advisory Committee on Antarctic Names in 2002 to honor Douglas R. MacAyeal of the Department of Geophysical Sciences, University of Chicago, a U.S. Antarctic Program investigator in the Ross Sea area including study of the Ross Ice Shelf, the West Antarctic Ice Sheet and the Marie Byrd Land ice streams, 1989–2002. Shabtaie Ice Ridge sits between the MacAyeal and Bundschadler ice streams.
Mercer Ice Stream, formerly Ice Stream A, flows west to Gould Coast to the south of Whillans Ice Stream, Antarctica. It is the southernmost of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. The ice streams were investigated and mapped by U.S. Antarctic Research Program personnel in a number of field seasons from 1983–84 and named Ice Stream A, B, C, etc., according to their position from south to north. The name was changed by the Advisory Committee on Antarctic Names in 2002 to honor Quaternary geologist John H. Mercer (1922–87) of the Institute of Polar Studies, Ohio State University, who mapped the moraines above Reedy Glacier and in the Ohio Range at the head of Horlick Ice Stream, the major tributaries to Mercer Ice Stream.
Anandakrishnan Glacier is a glacier about 15 nautical miles (30 km) long draining through the Ruppert Coast north of Strauss Glacier in Antarctica.
