The Whitmore Mountains ( 82°35′S 104°30′W  /  82.583°S 104.500°W  / -82.583; -104.500 ) are an isolated mountain range of the Transantarctic Mountains System, located in the Marie Byrd Land region of West Antarctica .

12-660: They consist of three mountains and a cluster of nunataks extending over 15 miles. The group was visited and surveyed on January 2, 1959, by William H. Chapman , cartographer with the Horlick Mountains Traverse Party (1958–59). The mountains were named by Chapman for George D. Whitmore, Chief Topographic Engineer of the United States Geological Survey (USGS), who was a member of the Working Group on Cartography of

24-652: Is a vast mountainous region located west of Dove Bay , King Frederik VIII Land , northeastern Greenland . Administratively it is part of the Northeast Greenland National Park zone. The highest point of Queen Louise Land is Gefiontinde , with a height of 2,364.3 m (7,757 ft), the highest of the Gefiontinder group of peaks located at 76°28′8″N 25°38′31″W  /  76.46889°N 25.64194°W  / 76.46889; -25.64194 . Geologically Queen Louise Land

36-473: Is made up of orthogneiss overlain by sedimentary rocks . This remote area was named Dronning Louises Land after Queen Louise of Denmark (1851–1926), wife of King Frederik VIII of Denmark , by the ill-fated 1906–08 Denmark Expedition —the expedition that aimed to map one of the last unknown parts of Greenland. Danish Arctic explorer Alf Trolle claimed that this area had been originally named as Den Store Nanuták —The Big Nunatak. Queen Louise Land

48-1079: Is the largest and highest mountain in the Whitmore Mountains, rising to 3,020 m (9,908 ft) at the northeast end of the group. It was surveyed on January 2, 1959, by William H. Chapman of USGS, a member of the Horlick Mountains Traverse Party, 1958–59. He named the mountain after Walter R. Seelig , Office of Polar Programs , National Science Foundation , 1960–86, who developed the USGS-NSF plan for topographic mapping of Antarctica; NSF Representative in Christchurch , N.Z., during eleven United States Antarctic Research Program (USARP) austral seasons between 1971 and 1986, including seventeen trips to Antarctica and adjacent seas; member, United States Advisory Committee on Antarctic Names , 1973–86; chairman, 1976–86. Nunatak A nunatak (from Inuit nunataq )

60-473: Is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They often form natural pyramidal peaks . Isolated nunataks are also called glacial islands, and smaller nunataks rounded by glacial action may be referred to as rognons . The word is of Greenlandic origin and has been used in English since the 1870s. The term nunatak

72-547: Is typically used in areas where a permanent ice sheet is present and the ridge protrudes above the sheet. Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some are isolated, they can also form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, hampering the formation of glacial ice on their tops, although snow can accumulate on them. This can contrast strongly with

84-564: The Horlick Mountains Traverse Party . William H. Chapman, party surveyor, proposed the naming for M. Kerwin Linck, Chief of the Branch of Special Maps of the USGS. Mount Radlinski ( 82°31′S 103°34′W  /  82.517°S 103.567°W  / -82.517; -103.567 ) is a rounded, smooth, ice-covered mountain (2,750 m) rising 4 miles southeast of Mount Seelig in the northeast part of

96-482: The Scientific Committee on Antarctic Research . Linck Nunataks ( 82°41′S 104°12′W  /  82.683°S 104.200°W  / -82.683; -104.200 ) is a group of four small, ice-covered nunataks at the southeast end of the Whitmore Mountains. Three of the nunataks are together and aligned while the fourth lies 2.5 miles distant. They were visited and surveyed on January 2, 1959, by

108-624: The Whitmore Mountains. It was surveyed on January 2, 1959, by William H. Chapman, a member of the Horlick Mountains Traverse (1958–59). Mount Radlinski was named by Chapman after William A. Radlinski, United States Geological Survey (USGS) photogrammetrist, 1949–79; associate director of USGS, 1969–79; president, American Society of Photogrammetry , 1968; president, International Federation of Surveyors , 1973–75. Mount Seelig ( 82°28′S 103°54′W  /  82.467°S 103.900°W  / -82.467; -103.900 )

120-544: The ice). Its western boundary is the Greenland ice sheet and its eastern limits are the massive Storstrommen and L. Bistrup Brae glaciers. Kap Aage Bertelsen is a small headland at the confluence of the large Storstrømmen and L. Bistrup Bræ glaciers in the east. Dryasdal is a valley seasonally covered with Dryas octopetala flowers. The area of Queen Louise Land is uninhabited. The main geographic divisions or parts of Queen Louise Land from north to south are: Many of

132-541: The softer contours of the glacially eroded land after a glacier retreats. They are not greatly affected by frost weathering , given the low frequency of freeze-thaw cycles in areas of ice caps and ice sheets. Typically nunataks are the only places where plant life can survive on ice sheets or ice caps. Lifeforms on nunataks are often isolated by the surrounding ice or glacier, providing unique habitats.

144-399: Was subsequently visited by the 1912–13 Danish Expedition to Queen Louise Land led by J.P. Koch , as well as the 1952–54 British North Greenland Expedition led by Commander James Simpson . Surrounded by ice masses, Queen Louise Land is clearly delimited. It is an extensive area made up of several very large and numerous small nunataks (summits or ridges of mountains that protrude from
