COMPOSITE GAZETTEER OF ANTARCTICA

rising to c. 3100m at Mount Stephenson, between 69°20' and 70°40'S, N Alexander Island, was sighted in its N part by FAE, 1908-10, in January 1909, when the names Île Gordon Bennett (Mount Edgell, q.v.) and Île Guernesey [sic] (Mount Guernsey, q.v.) were applied to unidentified peaks in the range, the true nature of the feature not being apparent (Bongrain, 1914, vue 39 following p.60); seen from the air in its S part by Ellsworth, 23 November 1935 (Stephenson and Hinks, 1940, p.177-80); seen from the air by BGLE, 13 March 1936, and roughly mapped from the E side (Stephenson, 1940, map facing p.232); named after Vice-Adm. Sir Henry Percy Douglas (1876-1939), Hydrographer of the Navy, 1924-32; member of the "Discovery" Committee, 1928-39; Chairman, Advisory Committee for BGLE (BA chart 3175, 1.iii.1940; APC, 1955, p.8; DOS 610 sheet W 69 68, 1963; Searle, 1963, Pl. 1; BAS 250P sheets SR 19-20/5 (Ext.) and 9, 1-DOS 1978). Cordón Douglas (Argentina. IGM map, 1946). Cordillera Douglas (Chile. DNH chart LIII, 1947). The range was resurveyed by FIDS from "Stonington Island", 1948-49. Cadena Douglas (Argentina. MM chart 110, 1949). Chaîne Douglas (France. SHM, 1954, p.49). Douglas-Gebirge, Douglas-Kette (Kosack, 1955a, p.227, end map). The range was photographed from the air by FIDASE, 1956-7, and mapped from air photographs by FIDS in 1959. Catena Douglas (Zavatti, 1958, Tav. 9). Khrebet Duglas (Soviet Union. MMF chart, 1961). Montes Douglas (Chile. DNH, 1962, p.202; IHA, 1974, p.105). [Cape Douglas, South Georgia, and Douglas Strait, South Sandwich Islands, are also named after Sir H.P. Douglas (Hattersley-Smith, 1980b, p.35).]

Sharp-crested range, with peaks rising to 3,000 m, extending 75 mi in a NW-SE direction from Mount Nicholas to Mount Edred and forming a steep E escarpment of Alexander Island, overlooking the N part of George VI Sound. Mount Nicholas was seen in 1909 from a distance by the FrAE under Charcot. The full extent of the range was observed by Lincoln Ellsworth on his trans-Antarctic flight of Nov. 23, 1935, and its E escarpment first roughly mapped from air photos taken on that flight by W.L.G. Joerg. The E face of the range was roughly surveyed from George VI Sound by the BGLE in 1936 and resurveyed by the FIDS in 1948-50. The entire range, including the W slopes, was mapped in detail from air photos taken by the RARE, 1947-48, by Searle of the FIDS in 1960. 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 British Navy.

El nombre fue puesto probablemente por el avión Douglas DC-6 B de la línea Aérea Nacional, que efectuó el primer vuelo comercial con pasajeros al Continente Antártico sobrevolando las bases chilenas sin aterrizar, el 22 de diciembre de 1956. Montes situados en la costa oriental de la isla Alejandro I, de una dirección SSE, son altos y acantilados, con una altura máxima de 2.499 metros.
