GEOGRAPHIC NAMES OF ANTARCTICA 



Blackwall Mtns. and Black Thumb Mtn., on the W. 

 coast of Palmer Pen.; in 68°23'S., 66°50'W. First 

 surveyed in 1936 by the BGLE under Rymill. Re- 

 surveyed in 1948-49 by the FIDS, who so named it 

 for its association with Remus Gl., whose head lies 

 near the head of this glacier. 



RONDE ISLET: small rocky islet lying close off 

 the NE. side of Zelee Glacier Tongue, about 2.6 mi. 

 WNW. of Rescape Islets, off AdeUe Coast; in about 

 66°47'S., 141°15'E. Photographed from the air by 

 USN Op. Hjp., 1946-47. Charted by the FrAE 

 under Liotard, 1949-51, and so named because of 

 its round shape. 



Ronne Bay: see Ronne Entrance. 



RONNE ENTRANCE : the broad SW. entrance of 

 George VI Sound where it opens on Bellingshausen 

 Sea between Alexander I Island and Robert English 

 Coast; in about 72°00'S., 76°00'W. This feature 

 was disc, on a sledge journey through the sound in 

 December 1940 by Finn Ronne and Carl Eklund of 

 the USAS, 1939-41. At that time it was named 

 Ronne Bay, the feature forming an open bay front- 

 ing on the ice shelf at the SW. end of the sound. 

 Since 1940, the head of Ronne Bay has receded east- 

 ward into George VI Sound altering the relation- 

 ships on which the name Ronne Bay was based. 

 The name Ronne Bay has therefore been dropped 

 and the name Ronne Entrance applied to the broad 

 SW. entrance of George VI Sound in keeping with 

 the physical characteristics of the feature. Named 

 for the Ronne family, of which the father, Martin 

 Ronne, was a member of the Nor. exp. under 

 Amundsen, 1910-12, and the ByrdAE, 1928-30, and 

 the son, Finn Ronne, was a member of the ByrdAE, 

 1933-35, and the USAS, 1939-41, and leader of the 

 RARE, 1947-48. Not adopted: Ronne Bay. 



Roocker, Mount: see Riicker, Mount. 



Rookery Islands: see Haswell Islets. 



Roosen Channel: see Neumayer Channel. 



ROOSEVELT ISLAND : ice-covered island, about 

 90 mi. long in a N.-S. direction and about 40 mi. 

 wide, lying in the E. part of the Ross Ice Shelf, with 

 its N. extremity about 3 mi. S. of the Bay of Whales; 

 in about 79°30'S., 162°00'W. Disc, in 1934 by the 

 ByrdAE, and named by R. Adm. Byrd for Franklin 

 D. Roosevelt, then President of the United States. 



Roosevelt Sea: see Amundsen Sea. 



ROOTS, MOUNT: mainly snow-covered moun- 

 tain in the AUardyce Range, South Georgia, stand- 

 ing near the head of Nordenskjold Gl., about 6 mi. 

 ESE. of Mt. Paget; in 54°28'S., 36°24'W. Its west- 



ern peak rises to about 7,500 ft. in el.; its eastern 

 peak to about 7,000 ft. The mountain is a promi- 

 nent feature and presumably was known to whalers 

 and sealers in South Georgia at an early date. It 

 was roughly surveyed in the period 1925-30 by DI 

 personnel, and resurveyed by the SGS, 1951-52. 

 Named by the Br-APC for James W. Roots, a mem- 

 ber of the SGS, 1951-52. 



ROPKE, MOUNT: mountain spur about 8,200 ft. 

 in el., on the W. side of the range forming the W. 

 wall of Penck Trough, in New Schwabenland; in 

 about 72°22'S., 5°30'W. Disc, by the GerAE under 

 Ritscher, 1938-39, and named for Karl-Heinz 

 Ropke, second officer of the exp. ship Schwaben- 

 land. Not adopted: Robke Berg [German], Ropke 

 Mountain. 



ROQUEMAUREL, CAPE : prominent rocky head- 

 land on the W. coast of Louis Philippe Pen., about 

 16 mi. NE. of Cape Kjellman; in 63°33'S., 58°56'W. 

 Disc, by a Fr. exp., 1837-40, under D'Urville, and 

 named by him for Lt. Louis De Roquemaurel, 

 second-in-command of the exp. ship Astrolabe. 



ROSA, CAPE : cape marking the S. side of the en- 

 trance to King Haakon Bay, on the S. coast of South 

 Georgia; in about 54°13'S., 37°22'W. The name 

 first appears about 1920 on charts of South Georgia 

 and has since become established by usage. 



ROSCOE GLACIER: channel glacier about 12 mi. 

 long and 3 to 5 mi. wide, flowing N. from the con- 

 tinental ice overlying Queen Mary Coast, and de- 

 bouching from a small valley onto the W. portion 

 of Shackleton Ice Shelf, midway between Cape 

 Moyes and Junction Corner; in about 66°45'S., 

 95°30'E. Charted as a valley depression during a 

 southern reconnaissance in March 1912 by F. Wild 

 and other members of the Western Base Party of 

 the AAE under Mawson. Delineated from aerial 

 photographs taken by USN Op. Hjp., 1946-47, and 

 named by the US-ACAN for John H. Roscoe, geog- 

 rapher, author of Antarctic Bibliography (Wash- 

 ington, 1951), and scientific advisor to the director 

 of United States Antarctic Programs. Roscoe 

 served as photogrammetrist with the central task 

 group of USN Op. Hjp., 1946-47, and with USN Op. 

 Wml., 1947-48, and assisted the latter group in es- 

 tablishing astronomical control stations along Wil- 

 helm II, Queen Mary, Knox and Budd Coasts. 



ROSEN WALD, MOUNT: prominent peak in the 

 higher foothills of the Queen Maud Range, stand- 

 ing NNW. of Mt. Black, on the W. side of Shackleton 

 GL; in about 85°08'S., 178°00'E. Disc, by R. Adm. 

 Byrd on ByrdAE flights to the Queen Maud Range 

 in November 1929, and named by him for Julius 

 Rosenwald of Chicago, contributor to the Byrd Ant- 

 arctic Expeditions of 1928-30 and 1933-35.
