The Lexington Table (83°05′S 49°45′W / 83.083°S 49.750°W) is 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 in the Forrestal Range, Pensacola Mountains, Antarctica.[1]
Discovery and name
[edit]The Lexington Table was discovered and photographed on January 13, 1956 on a transcontinental nonstop flight by personnel 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) for the USS Lexington of 1926, one of the first large aircraft carriers of the United States Navy.[1]
Location
[edit]
The Lexington Table is north of the Saratoga Table, from which it is separated by the May Valley, Kent Gap and Chambers Glacier. The Support Force Glacier runs along its eastern side. Features, clockwise from the northeast, include Franko Escarpment, McCauley Rock, Ritala Spur, Mount Zirzow, Kovacs Glacier, Mount Mann, Watts Summit, Cooke Crags, Henderson Bluff and Hodge Escarpment. Features to the southwest include Camp Spur, Mount Lechner, Erlanger Spur, Blount Nunatak, Abele Spur, Creaney Nunataks and Herring Nunataks.[2]
