GEOGRAPHIC NAMES OF ANTARCTICA 



1948 by the FIDS. The name was first used by 

 BGLE sledging parties because these mountains 

 are an important landmark in the overland trav- 

 erse from the Wordie Ice Shelf, down Eureka Gl., 

 to George VI Sound. 



TRENCH GLACIER: deeply entrenched glacier 

 on the E. coast of Alexander I Island, about 6 mi. 

 long and 2 mi. wide, which flows eastward into 

 George VI Sound immediately S. of Mt. Athelstan; 

 in 70°12'S., 69°11'W. The mouth of this glacier 

 was first photographed from the air on Nov. 23, 

 1935 by Lincoln Ellsworth, and it was mapped from 

 these photographs by W. L. G. Joerg. Trench 

 Glacier was surveyed in 1948 and 1949 by the 

 FIDS, who applied this descriptive name. 



TREPASSEY ISLETS: two small rocky islets 0.6 

 mi. SE. of Stonington I. in Neny Bay, off the W. 

 coast of Palmer Pen.; in 68°12'S., 66°59'W. The 

 islets were presumably first sighted in 1936 by the 

 BGLE, and were roughly charted by them and by 

 the USAS, 1939-41. They were surveyed in 1947 

 by the FIDS and named for the M.V. Trepassey, 

 ship used by the FIDS in establishing a base on 

 Stonington I. in 1946. 



TRETHEWRY POINT: rocky promontory about 

 400 ft. in el., projecting about 1 mi. N. into the sea 

 along Mac-Robertson Coast, about 5 mi. E. of Wil- 

 Uam Scoresby Bay; in about 67°24'S., 59°51'E. 

 Disc, and named in February 1936 by DI personnel 

 on the William Scoresby. Not adopted: Hamre- 

 hovden [Norwegian]. 



TRIANGLE POINT: triangular headland form- 

 ing the outer NW. side of the entrance to Yankee 

 Hbr. on Greenwich I., in the South Shetland Is.; 

 62°31'S., 59°52'W. Charted by DI personnel on 

 the Discovery II in 1935 and given this descriptive 

 name. 



TRICORN, MOUNT: distinctive massif whose 

 vertical faces rise to about 4,000 ft. in el., and sur- 

 round a snow-covered interior which is lower ex- 

 cept for a 5,300 ft. peak in the NW. portion, stand- 

 ing at the head of Wright Inlet on the E. coast of 

 Palmer Pen.; in 73°58'S., 61°45'W. Disc, by mem- 

 bers of the USAS in a flight from East Base on 

 Dec. 30, 1940, and named for its resemblance to a 

 gigantic tri-cornered hat. 



Tricorn Inlet, Mount: see Wright Inlet. 



TRIGONIA ISLET: islet immediately off the S. 

 tip of Beer I., lying about 9 mi. W. of Ferin Head, 

 off the W. coast of Palmer Pen.; in 66°01'S., 

 65°44'W. Charted and named by the BGLE, 1934- 

 37, Rymill. 



Trillingnutane: see Trilling Peaks. 



TRILLING PEAKS: a series of three N.-S. 

 trending peaks, the highest about 4,400 ft. in el., 

 standing in the S. part of the Masson Range of 

 the Framnes Mtns., on Mac-Robertson Coast; in 

 about 67°58'S., 62°47'E. Mapped by Norwegian 

 cartographers from aerial photographs taken by a 

 Nor. exp. under Christensen in January 1937. 

 The name is descriptive, meaning "the triplet 

 peaks." Not adopted: Trillingnutane [Norwegian]. 



Trinite, He de la: see Trinity Island. 



TRINITY ISLAND: island about 15 mi. long and 

 13 mi. wide, which is separated from the W. coast 

 of Palmer Pen. by Orleans Chan.; in 63°45'S., 

 60°40'W. Named by Dr. Otto Nordenskjold, leader 

 of the SwedAE, 1901-4, in commemoration of Ed- 

 ward Bransfield's Trinity Land of 1820, which is 

 now thought to be this island. Not adopted: He 

 de la Trinite [French] . 



TRINITY ISLET: islet about 0.5 mi. NE. of the 

 NE. end of Main I., in the Willis Is. at South 

 Georgia; in 54°00'S., 38°13'W. Charted and 

 named by DI personnel in the period 1926-30. Not 

 adopted : Trinity Island. 



Trinity Peninsula: see Louis Philippe Peninsula; 

 Palmer Peninsula. 



Trio, Islotes: see Tau Islets. 



TRIPLE ISLETS: three small rocky islets, lying 

 in a closely-spaced chain close E. of the tip of 

 Zelee Glacier Tongue, about 0.4 mi. SSE. of Double 

 Its., off Adelie Coast; in about 66°46'S., 141°12'E. 

 Photographed from the air by USN Op. Hjp., 1946- 

 47. Charted and named by the FrAE under Llo- 

 tard, 1949-51. 



TRIPLETS, THE: a three-pointed peak at the 

 SE. side of Coppermine Cove, near the NW. end of 

 Robert I., in the South Shetland Is.; in 62°23'S., 

 59°45'W. The name appears to have been applied 

 by DI personnel on the Discovery II, who charted 

 the peak in 1935. 



Tripode, Islote: see Tripod Islet, 



TRIPOD ISLET: small islet which lies close S. 

 of the W. extremity of Eta I. and marks the N. 

 side of the western entrance to Andersen Harbor 

 in the Melchior Is., Palmer Arch.; in 64°19'S., 

 62°57'W. The name was probably given by DI 

 personnel who roughly surveyed the islet in 1927. 

 The islet was surveyed by Argentine expeditions in 

 1942, 1943 and 1948. Not adopted: Islote Tripode 

 [Spanish] .
