GEOGRAPHIC NAMES OF ANTARCTICA 



given this descriptive name by the FrAE, 1908-10, 

 under Charcot. Not adopted: La Tour [French]. 



TOWER HILL: sharp conical summit about 3,700 

 ft. in el., near the center of Trinity I., which is sepa- 

 rated from the W. coast of Palmer Pen. by Orleans 

 Chan.; in 63°46'S., 60°39'W. The origin of the 

 name is not known, but it may be associated with 

 the voyage in 1824-25 of the British sealer 

 Sprightly under Capt. Edward Hughes. 



TOWER ISLAND: island about 4 mi. long, lying 

 NE. of Trinity I., about 11 mi. off the W. coast of 

 Palmer Pen.; in 63°33'S., 59°51'W. Named on Jan. 

 30, 1820 by a Br. exp. under Bransfield. Not 

 adopted: Pendleton Island. 



TOWER PEAK: peak, about 2,800 ft. in el., whose 

 rock exposure stands out clearly from an evenly 

 contoured ice field, standing about 9 mi. SW. of 

 Sjogren Gl., on the E. coast of Palmer Pen.; in 

 64°22'S., 59°08'W. First charted and given this 

 descriptive name by the FIDS, 1945. 



TOYNBEE GLACIER: glacier in NE. Alexander 

 I Island, about 20 mi. long and 5 mi. wide, lying 

 between the mountains of the Douglas Range on 

 the W. and Mt. Tyrrell and Mt. Tilley on the E. and 

 flowing N. from Mt. Stephenson to George VI 

 Sound; in 69°35'S., 69°35'W. First photographed 

 from the air in 1937 by the BGLE under Rymill. 

 Surveyed from the ground in 1948 by the FIDS, 

 and named for Patrick A. Toynbee, FIDS air pilot 

 at Stonington I. in 1948 and 1949. 



TRACY GLACIER: channel glacier about 7 mi. 

 wide and 8 mi. long, marked by prominent ice falls 

 along its E. flank, flowing NNW. from the conti- 

 nental ice to the Knox Coast, about 8 mi. SW. of 

 Cape Elliott, in about 66°02'S., 102°08'E. Deline- 

 ated from aerial photographs taken by USN Op. 

 Hjp., 1946-47, and named by the US-ACAN for Lt. 

 Lloyd W. Tracy, USN, pilot with USN Op. Wml., 

 1947-48, who assisted in operations which resulted 

 in the establishment of astronomical control sta- 

 tions from Wilhelm II Coast to Budd Coast. 



TRAFFIC CIRCLE, THE: an ice-filled depression 

 at an elevation of 2,800 ft. centered in about 

 68°37'S., 66°00'W. on Palmer Pen., between Mar- 

 guerite Bay and Mobiloil Inlet. From this depres- 

 sion five glacier-filled troughs radiate like the 

 spokes of a wheel. One connects on the N. with 

 Neny Trough. Another is filled by Lammers Gl. 

 and trends W. to an ice-covered upland in 66°40'W. 

 which also nourishes the west-flowing glacier filling 

 Windy Valley. A third trends SW. to the S. end 

 of the ice-covered upland in 66°40'W. which nour- 

 ishes the southwest-flowing glacier along the E. 

 side of Sickle Mtn. The fourth, filled by Weyer- 



haeuser Gl., trends SSW. to the N. flank of Bing- 

 ham Gl. The fifth, filled by the outflow from 

 Weyerhaeuser and Lammers Glaciers and the gla- 

 cier filling Neny Trough, broadens as it descends 

 E. to the head of Mobiloil Inlet. Disc, in 1940 by 

 members of the East Base of USAS who used this 

 system of troughs in traveling across the upland, 

 hence its name. 



Trail Bay: see Trail Inlet. 



TRAIL INLET: ice-filled inlet which recedes SW. 

 about 15 mi. between Three Slice Nunatak and 

 Cape Freeman, along the E. coast of Palmer Pen.; 

 in 68°05'S., 65°20'W. The inlet was sighted by Sir 

 Hubert Wilkins on his flight of Dec. 20, 1928. The 

 width of Palmer Pen. is reduced to 20 mi. between 

 the head of Trail Inlet on the east and Neny Fjord 

 on the west. So named by the US-SCAN because 

 it formed a natural route of travel for flights and 

 sledge trips from the East Base of the USAS, 

 1939-41, to the E. coast of Palmer Peninsula. Not 

 adopted: Trail Bay. 



TRANSITION GLACIER: glacier on the E. coast 

 of Alexander I Island, about 8 mi. long and 2 mi. 

 wide, which flows E. to George VI Sound along 

 the N. side of Block Mtn. and Tilt Rock; in 70°26'S., 

 68°49'W. This glacier was flrst photographed 

 from the air on Nov. 23, 1935 by Lincoln Ellsworth, 

 and was mapped from these photographs by W. L. 

 G. Joerg. Surveyed in 1949 by the FIDS, and so 

 named by them because this glacier marks the 

 transition between igneous rocks to the north and 

 sedimentary rocks to the south. 



TRAVERSE ISLANDS: group of three islands, 

 consisting of Zavodovski, Leskov, and Visokoi Is- 

 lands, at the N. end of the South Sandwich Is.; 

 centering in 56°36'S., 27°43'W. The group was 

 disc, in 1819 by a Russ. exp. under Bellingshausen, 

 who named them for Baron de Traversey, Russian 

 naval minister who aided in the organization of 

 the exp. The present spelling omitting the "y" is 

 due to the variation in the form of Russian family 

 names resulting from the type of Western Euro- 

 pean transliteration used by the bearers of a given 

 name and is now well established in international 

 usage. 



TRAVERSE MOUNTAINS: group of almost ice- 

 free mountains, about 4,100 ft. in el., standing at 

 the S. side of Eureka GL, about 6 mi. inland from 

 George VI Sound, on the W. side of Palmer Pen.; 

 in 69°51'S., 68°02'W. These mountains were first 

 photographed from the air on Nov. 23, 1935 by 

 Lincoln Ellsworth, and were mapped from these 

 photographs by W. L. G. Joerg. First surveyed in 

 1936 by the BGLE under Rymill, and resurveyed in
