 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 is the highest mountain in the Antarctic Peninsula and the British Antarctic Territory . 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 . 
 Mount Jackson and the Welch Mountains demarcate the central Black Coast , which is dissected by many inlets and is bounded on the west by Dyer Plateau of central Palmer Land . The two mountains rise above the ice shelf with reliefs of about 1 @,@ 200 – 1 @,@ 500 metres ( 3 @,@ 900 – 4 @,@ 900 ft ) towards the east . They are interconnected by icefall zones forming a plateau with steep snow slopes . Mount Jackson rises from its southeast flanks , displaying a steeple summit , while the north flank is occupied by a vast cirque . Supraglacial moraines on the mountain 's east side measure between 1 – 5 kilometres ( 0 @.@ 62 – 3 @.@ 11 mi ) in length and display boulders at their distal ends .

 The first topographic mapping of Mount Jackson was carried out in November 1940 by a sledge party of the United States Antarctic Service ( USAS ) . The ground survey was facilitated by aerial photographs and aerial observations . The height was estimated at 4 @,@ 200 metres ( 13 @,@ 800 ft ) , and the mountain was named Mount Ernest Gruening after the Governor of the Alaska Territory at that time , Ernest Gruening . USAS later renamed it Mount Jackson for the seventh President of the United States . President Jackson signed the bill into law authorizing the United States Exploring Expedition of 1838 – 42 . The expedition , led by Lt. Charles Wilkes , included exploration and surveying of the Pacific Ocean and surrounding lands , including Antarctica . 
 In November 1947 , a Falkland Islands Dependencies Survey ( FIDS ) ground party based at Stonington Island observed Mount Jackson and estimated its height at 3 @,@ 050 metres ( 10 @,@ 010 ft ) , considerably lower and more accurate than the first estimate in 1940 . 
 After the Falkland Islands Dependencies Survey was renamed British Antarctic Survey in 1962 , a series of depots were developed , including one at Mount Jackson . BAS members were successful in making many first ascents of the mountains of the Antarctic Peninsula , and John Cunningham , who served at the BAS base at Adelaide Island , was the first to climb Mount Jackson . Traveling by dog sled for 640 kilometres ( 400 mi ) , his team reached the summit on 23 November 1964 . 
 A precise height of the summit was determined by a BAS survey party who ascended the peak during the austral summer of 1996 – 97 .

 The mountain is 3 @,@ 184 metres ( 10 @,@ 446 ft ) in height , with a prominence of 2 @,@ 187 metres ( 7 @,@ 175 ft ) and a saddle DEM of 997 metres ( 3 @,@ 271 ft ) . Mount Jackson and the Welch Mountains demarcate the central Black Coast , which is dissected by many inlets and is bounded on the west by Dyer Plateau of central Palmer Land , with elevation ranging between 2 @,@ 000 – 3 @,@ 000 metres ( 6 @,@ 600 – 9 @,@ 800 ft ) , and on the west side of the central Black Coast . The two mountains rise above the ice shelf with reliefs of about 1 @,@ 200 – 1 @,@ 500 metres ( 3 @,@ 900 – 4 @,@ 900 ft ) towards the east . They are interconnected by icefall zones forming a plateau with steep snow slopes . The northern part of the mountain system , which extends over 1 @,@ 590 kilometres ( 990 mi ) , covers most of the Antarctic Peninsula , and Mount Jackson is its highest peak . 
 Mount Jackson rises from its southeast flanks , displaying a steeple summit , while the north flank is occupied by a vast cirque . Supraglacial moraines on the mountain 's east side measure between 1 – 5 kilometres ( 0 @.@ 62 – 3 @.@ 11 mi ) in length and display boulders at their distal ends . Mount Jackson and the Rowley Massif are separated by Odom Inlet . Cline Glacier drains eastern Mount Jackson before arriving at Odom Inlet . 
 Mount Jackson 's geology was studied in 1972 as part of the Palmer Island investigations by a team of geologists . They identified various rock types and underlying volcanic activity . The relief of the west facing slopes is gentler when compared to the eastern side , characterized by a steep rocky face . Rock weathering is intense in the area spread with scree and felsenmeer . Fresh rock formations and bedrock disintegration are noted .
