Mount Jackson

Mount Jackson (Mount Andrew Jackson and Mount Ernest Gruening) is a mountain that dominates the upland of the southern part of the Antarctic Peninsula. It is located in Palmer Land, within the Antarctic claims of Argentina, Chile and the United Kingdom.

With an elevation of 3,184 metres (10,446 ft), Mount Jackson was once thought to be the highest mountain in the Antarctic Peninsula and the British Antarctic Territory, before the true height of Mount Hope (Eternity Range) was measured.

Discovered by members of the United States Antarctic Service, 1939–41, it was named for Andrew Jackson, the seventh President of the United States. The first ascent of Mount Jackson was made by a team led by John Crabbe Cunningham of the British Antarctic Survey (BAS) in 1964. Mount Jackson's geology was studied in 1972 as part of the Palmer Island investigations by a team of geologists.
