This is a list of the extreme points of the United Kingdom: the points that are farther north, south, east or west than any other location. Traditionally the extent of the island of Great Britain has stretched "from Land's End to John o' Groats".
Thurston Island is a largely ice-covered, glacially dissected island, 135 nautical miles long and 55 nautical miles wide, lying between Amundsen Sea and Bellingshausen Sea a short way off the northwest end of Ellsworth Land, Antarctica. The island is separated from the mainland by Peacock Sound, which is occupied by the west portion of Abbot Ice Shelf.
Skelton Glacier is a large glacier flowing from the polar plateau into the Ross Ice Shelf at Skelton Inlet on the Hillary Coast, south of Victoria Land, Antarctica.
The Alexandra Mountains are a group of low, separated mountains in the north portion of Edward VII Peninsula, just southwest of Sulzberger Bay in Marie Byrd Land, Antarctica.
The Neptune Range is a mountain range, 70 nautical miles long, lying west-southwest of Forrestal Range in the central part of the Pensacola Mountains, Antarctica. The range comprises Washington Escarpment with its associated ridges, valleys and peaks, the Iroquois Plateau, the Schmidt and the Williams Hills.
The Reedy Glacier is a major glacier in Antarctica, over 100 nautical miles long and 6 to 12 nautical miles wide, descending from the polar plateau to the Ross Ice Shelf between the Michigan Plateau and Wisconsin Range in the Transantarctic Mountains. It marks the limits of the Queen Maud Mountains on the west and the Horlick Mountains on the east.
The Axel Heiberg Glacier in Antarctica is a valley glacier, 30 nautical miles long, descending from the high elevations of the Antarctic Plateau into the Ross Ice Shelf between the Herbert Range and Mount Don Pedro Christophersen in the Queen Maud Mountains.
Joinville Island is the largest island of the Joinville Island group, about 40 nautical miles long in an east–west direction and 12 nautical miles wide, lying off the northeastern tip of the Antarctic Peninsula, from which it is separated by the Antarctic Sound.
Tucker Glacier is a major valley glacier of Victoria Land, Antarctica, about 90 nautical miles long, flowing southeast between the Admiralty Mountains and the Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which the Ebbe Glacier flows northwestward.
The Victory Mountains is a major group of mountains in Victoria Land, Antarctica, about 100 nautical miles long and 50 nautical miles wide, which is bounded primarily by Mariner and Tucker glaciers and the Ross Sea. They are north of the Mountaineer Range, east of the Freyberg Mountains and south of the Concord Mountains and the Admiralty Mountains. The division between the Victory Mountains and the Concord Mountains is not precise but apparently lies in the vicinity of Thomson Peak.
The Hauberg Mountains are a group of mountains of about 35 nautical miles extent, located 12 nautical miles north of Cape Zumberge and 30 nautical miles south of the Sweeney Mountains in eastern Ellsworth Land, Antarctica.
Koettlitz Glacier is a large Antarctic glacier lying west of Mount Morning and Mount Discovery in the Royal Society Range, flowing from the vicinity of Mount Cocks northeastward between Brown Peninsula and the mainland into the ice shelf of McMurdo Sound.
Liv Glacier is a steep valley glacier, 40 nautical miles long, emerging from the Antarctic Plateau just southeast of Barnum Peak and draining north through the Queen Maud Mountains to enter Ross Ice Shelf between Mayer Crags and Duncan Mountains. It was discovered in 1911 by Roald Amundsen, who named it for the daughter of Fridtjof Nansen.
The Porthos Range is the second range south in the Prince Charles Mountains of Antarctica, extending for about 30 miles in an east-to-west direction between Scylla Glacier and Charybdis Glacier. First visited in December 1956 by the Australian National Antarctic Research Expeditions (ANARE) southern party under W.G. Bewsher (1956-57) and named after Porthos, a character in Alexandre Dumas, père's novel The Three Musketeers, the most popular book read on the southern journey.
Allen Point is the southeast point of Montagu Island, in the South Sandwich Islands. Montagu Island was discovered in 1775 by a British expedition under James Cook, but the point was first mapped by Fabian Gottlieb von Bellingshausen in 1819–20. The point was surveyed in 1930 by Discovery Investigations personnel on the Discovery II and named for H.T. Allen, a member of the Discovery Committee.
Condor Peninsula is a mountainous, ice-covered peninsula, 30 nautical miles long and 10 to 15 nautical miles wide, between Odom Inlet and Hilton Inlet on the east coast of Palmer Land, Antarctica.
The Denfeld Mountains are a group of scattered mountains between Crevasse Valley Glacier and Arthur Glacier in the Ford Ranges of Marie Byrd Land, Antarctica.
Longlow Rock is a rock 1 nautical mile (2 km) south-southwest of Borley Point and 0.5 nautical miles (1 km) off the west shore of Montagu Island, in the South Sandwich Islands. It was charted and named in 1930 by Discovery Investigations personnel on the Discovery II.
The Malta Plateau is an ice-covered plateau of about 25 nautical miles extent in the Victory Mountains of Victoria Land, Antarctica. The plateau is irregular in shape and is bounded on the south and west by Mariner Glacier, on the north by tributaries to Trafalgar Glacier, and on the east by tributaries to Borchgrevink Glacier.
The Erb Range is a rugged mountain range rising to 2,240 metres (7,350 ft) between Kosco Glacier and Shackleton Glacier in the Queen Maud Mountains, and extending north from Anderson Heights to Mount Speed on the west side of the Ross Ice Shelf.
