Forrestal Range
The Forrestal Range (83°00′S 049°30′W / 83.000°S 49.500°W) is a largely snow-covered mountain range, about 65 nautical miles (120 km; 75 mi) long, standing east of Dufek Massif and the Neptune Range in the Pensacola Mountains, Antarctica.[1]
Discovery and name
[edit]The Forrestal Range was discovered and photographed on 13 January 1956 on a transcontinental patrol plane flight of United States Navy Operation Deep Freeze I from McMurdo Sound to the vicinity of the Weddell Sea and return. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after USS Forrestal, first supercarrier of the U.S. Navy. The entire Pensacola Mountains were mapped by United States Geological Survey (USGS) in 1967 and 1968 from United States Navy tricamera aerial photographs taken in 1964.[1]
Location
[edit]
The Forrestal Range extends in a north-northeast direction along the west side of the Support Force Glacier. The Median Snowfield is to its south and the Sallee Snowfield to its west, separating it from the Dufek Massif. The Ford Ice Piedmont is to its north. Major features from south to north include the Saratoga Table, Lexington Table, Kester Peaks and Mount Malville.[2][3]
Major glaciers and snowfields
[edit]- Support Force Glacier (82°45′S 046°30′W / 82.750°S 46.500°W), a major glacier in the Pensacola Mountains, draining northward between the Forrestal Range and Argentina Range to the Filchner-Ronne Ice Shelf.[4]
- Median Snowfield (83°30′S 52°30′W / 83.500°S 52.500°W), a large snowfield in the Pensacola Mountains between Torbert Escarpment and the southern part of the Forrestal Range.[5]
- Sallee Snowfield (82°37′S 50°20′W / 82.617°S 50.333°W), a large snowfield between the Dufek Massif and northern Forrestal Range.[6]
- Ford Ice Piedmont (82°10′S 50°00′W / 82.167°S 50.000°W), the large ice piedmont lying northward of Dufek Massif and Forrestal Range between the lower ends of Foundation Ice Stream and Support Force Glacier.[7]

- Lexington Table (83°05′S 49°45′W / 83.083°S 49.750°W), a high, flat, snow-covered plateau, about 15 nautical miles (28 km; 17 mi) long and 10 nautical miles (19 km; 12 mi) wide, standing just north of Kent Gap and Saratoga Table.[10]
- Saratoga Table (83°20′S 50°30′W / 83.333°S 50.500°W) , a high, flat, snow-covered plateau, 8 nautical miles (15 km; 9.2 mi) long and 6 nautical miles (11 km; 6.9 mi) wide, standing just south of Kent Gap and Lexington Table in the southern Forrestal Range.[11]
