near SE end of Dyer Plateau, central Palmer Land, long heald to be the highest peak (3180m) in the British Antarctic Territory until a resurvey put its height at 10,446 feet and that of Mount Hope (q.v.) at 10,626 feet. The mountain was seen from the air and from the ground by the United States Antarctic Service in November 1940, when its height was estimated as c. 4200m; called Mount Ernest Gruening after Ernest H. Gruening (Gruening Glacier, q.v.) and shown in 71°21'S 63°10'W; later named Mount Andrew Jackson after Andrew Jackson (1767-1845), 7th President of the United States, 1828-36, who signed the bill authorizing the United States Exploring Expedition, 1838-42. The mountain was seen from the ground from a distance by a Falkland Islands Dependencies Survey party from 'Stonington Island' in November 1947, when its height was estimated as more than 3050m but lower than previously reported. The mountain was surveyed by the British Antarctic Survey from Adelaide in 1964, when the first ascent was made on 23 November. The mountain was photographed from the air by the United States Navy, 1966-69, and mapped from air photographs by the United States Geological Survey.
