History
The first topographic mapping of Mount Jackson was carried out in November 1940 by a sledge party of the
In November 1947, a Falkland Islands Dependencies Survey 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.[7]
After the Falkland Islands Dependencies Survey was renamed the British Antarctic Survey in 1962, a series of depots were developed, including one at Mount Jackson.[8] 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),[9] his team reached the summit on 23 November 1964.[7][6][10]
A precise height of the summit was determined by a BAS survey party who ascended the peak during the austral summer of 1996–97.[1]
Geography
The mountain is 3,184 metres (10,446 ft) in height,[1] with a prominence of 1,384 metres (4,541 ft) and a saddle DEM of 1,901 metres (6,237 ft).[11] 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),[12] and on the west side of the central Black Coast.[13] 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.[14] 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.[1][15][16]
Mount Jackson rises from its southeast flanks, displaying a steeple summit,
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.
Nearby features
Nnearby features include, from north to south, Mount Van Buren, Swarson Nunatak, Davis Ridge and Musson Nunatak.[21]
Mount Van Buren
71°18′S 63°30′W / 71.300°S 63.500°W. The prominent mountain 3 nautical miles (5.6 km; 3.5 mi) north-northwest of Mount Jackson, at the east side of the Dyer Plateau. Mapped by the United States Geological Survey (USGS) in 1974. The name was applied by the United States Advisory Committee on Antarctic Names (US-ACAN) in association with Mount Jackson. Martin Van Buren (1782-1862) was the eighth President of the United States, 1837-41. He was Vice President, 1833-37, during the second term of President Andrew Jackson.[22]
Swarsen Nunatak
71°25′S 63°39′W / 71.417°S 63.650°W. A conspicuous nunatak, largely snow covered, located 5 nautical miles (9.3 km; 5.8 mi) southwest of Mount Jackson. Mapped by the USGS in 1974. Named by the US-ACAN for Lieutenant Commander Ronald J. Swarsen, United States Navy Reserve, Medical Officer at
Davis Ridge
71°24′S 63°00′W / 71.400°S 63.000°W. A ridge of irregular shape, apparently an outlier of the Mount Jackson massif. It rises above the ice surface 6 nautical miles (11 km; 6.9 mi) east-southeast of the summit of Mount Jackson. Mapped by the USGS in 1974. Named by the US-ACAN for Brent L. Davis, USARP biologist at Palmer Station, 1971, and in the Antarctic Peninsula area, 1974-75 season.[24]
Musson Nunatak
71°31′S 63°27′W / 71.517°S 63.450°W. A pyramidal nunatak standing 10 nautical miles (19 km; 12 mi) south of Mount Jackson, at the east margin of the Dyer Plateau. Mapped by the USGS in 1974. Named by the US-ACAN for John M. Musson, PH2, United States Navy, photographer and member of the cartographic aerial mapping crew in LC-130 aircraft of Squadron VXE-6, 1968-69.[25]
