Douglas Range

The Douglas Range (70°0′S 69°35′W) is a sharp-crested range, with peaks rising to 3,000 metres, extending 120 km (75 mi) in a northwest–southeast direction from Mount Nicholas to Mount Edred and forming a steep east escarpment of Alexander Island within the British Antarctic Territory, overlooking the north part of George VI Sound.

Not to be confused with Douglas Ranges, in British Columbia, Canada.

History

Mount Nicholas was seen in 1909 from a distance by the French Antarctic Expedition under Charcot. The full extent of the range was observed by Lincoln Ellsworth on his trans-Antarctic flight of November 23, 1935, and its east escarpment first roughly mapped from air photos taken on that flight by W.L.G. Joerg. The east face of the range was roughly surveyed from George VI Sound by the British Graham Land Expedition (BGLE) in 1936 and resurveyed by the Falkland Islands Dependencies Survey (FIDS) in 1948–50. The entire range, including the west slopes, was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the FIDS in 1960.

The Douglas Range was named by the BGLE, 1934–37, for V. Admiral Sir Percy Douglas, chairman of the BGLE Advisory Committee, member of the Discovery Committee from 1928 until his death in 1939, formerly hydrographer of the Royal Navy.
