GEOGRAPHIC NAMES OF ANTARCTICA 



the Wordie Ice Shelf, down Eureka Gl., to George 

 VI Sound. 



TERN COVE: small cove, the entrance to which 

 is blocked by submerged rocks, lying immediately 

 SE. of Berry Head on the E. side of Signy I., South 

 Orkney Is.; in 60°42'S., 45°37'W. The cove con- 

 tains three islets, and an area near the head dries 

 at low water. Roughly charted in 1933 by DI per- 

 sonnel. Named by the FIDS, following their sur- 

 vey of 1947, after the? colony of terns {Sterna vit- 

 tata) on the southernmost islet in the cove. 



TERN ISLET: small, tussock grass covered islet, 

 lying 1 mi. S. of Albatross I. and 0.5 mi. E. of Dot 

 It. in the S. part of the Bay of Isles, South Georgia; 

 in 54°03'S., 37°20'W. First charted in 1912-13 by 

 Robert Cushman Murphy, American naturalist 

 aboard the brig Daisy. It was surveyed in 1929-30 

 by DI personnel, who named it Tern Island in as- 

 sociation with Albatross I., Prion I. and other nat- 

 ural history names in the Bay of Isles given by 

 Murphy in 1912-13. The name Tern Islet is ap- 

 proved because of the small size of the feature. 

 Not adopted: Tern Island. 



TERNYCK NEEDLE: conspicuous nunatak 

 standing about 2.5 mi. E. of Ullmann Range, at the 

 base of the small peninsula separating Admiralty 

 and King George Bays, on King George I., in the 

 South Shetland Is.; in 62°03'S., 58°15'W. Charted 

 in December 1909 by the FrAE under Charcot, who 

 presumably applied the name. 



Terrace Island: see Dunlop Island. 



TERRA FIRMA ISLANDS : small group of islands 

 lying about 7 mi. N. of Cape Berteaux, off the W. 

 coast of Palmer Pen.; in 68°42'S., 67°32'W. Disc, 

 and named on June 18, 1936 by the BGLE under 

 Rymill. 



Terra Firma II island: see Twig Rock. 



TERRA NOVA, MOUNT: snow-covered mountain 

 standing between Mt. Erebus and Mt. Terror on 

 Ross I.; in about 77°31'S., 168°05'E. First charted 

 by the BrNAE, 1901-4, under Scott, who named it 

 for the Terra 'Nova, relief ship for this exp.; also, 

 exp. ship for the BrAE, 1910-13, under Scott. 



TERRA NOVA BAY: bay, often ice free, about 

 55 mi. long, lying between Cape Washington and 

 Drygalski Ice Tongue along the E. coast of Vic- 

 toria Land; in about 74°45'S., 164°15'E. Disc, by 

 the BrNAE, 1901-4, under Scott, and named by him 

 for the Terra Nova, one of the relief ships for this 

 expedition. 



TERRAPIN HILL: rounded, reddish-colored hill, 

 1,600 ft. in el., standing at the S. end of The Naze, 

 a peninsula of northern James Ross I., close S. of 

 the NE. end of Palmer Pen.; in 63°58'S., 57°32'W. 

 This area was first explored by the SwedAE, 1901-4, 

 under Nordenskjold. Terrapin Hill was first 

 charted by the FIDS, 1945, who applied this de- 

 scriptive name. 



Terre du Roi Oscar: see Oscar II Coast. 



Terre Otto Nordenskjold: see Nordenskjold Coast. 



TERROR, MOUNT: an extinct volcano, about 

 10,750 ft. in el., standing about 20 mi. E. of Mt. 

 Erebus on Ross I.; in about 77°30'S., 168°40'E. 

 Disc, in 1841 by a Br. exp. under Ross, who named 

 it for his second exp. ship, the Terror. 



TETHYS NUNATAKS: group of about five rock 

 nunataks, lying 2 mi. NE. of Stephenson Nunatak 

 near the SE. corner of Alexander I Island; in 

 72°10'S., 68°59'W. These rocks were presumably 

 first seen by members of the USAS who sledged 

 through George VI Sound in 1940-41. They were 

 visited and surveyed in 1949 by the FIDS. Named 

 by the FIDS for their association with nearby 

 Saturn Glacier; Tethys being one of the satellites 

 of Saturn. 



Teufelsinsel: see Devil Island. 



THANARON HILL: ice-covered hill, 2,900 ft. in 

 el., which with two lower summits forms an isolated 

 mountain, about 4 mi. SE. of Cape Roquemaurel, 

 on the NW. coast of Louis Philippe Pen.; in 63°35'S., 

 58°48'W. Capt. Dumont D'Urville, leader of the 

 Fr. exp., 1837-40, originally gave the name Than- 

 aron, after Lt. Charles Thanaron of the exp. ship 

 Zelee, to a cape in this area. A survey by the FIDS 

 in 1946 determined that no cape exists. The name 

 Thanaron, however, is retained for the ice-covered 

 hill in the same area. Not adopted: Cap Tannaron 

 [French] . 



THEODOLITE HILL; hill, about 2,600 ft. in el., 

 with a small rock outcrop at its summit, standing 

 at the SE. corner of a plateau-type mountain, about 

 4.5 mi. W. of the NW. end of Duse Bay and about 

 7 mi. NW. of View Pt., near the NE. end of Palmer 

 Pen.; in 63°29'S., 57°35'W. Disc, by the FIDS, 

 1946, and so named during their survey of the 

 area because it served as an important theodolite 

 station. 



THEODOR ROCK: rock approximately midway 

 between Annenkov I. and Pickersgill Is., off the S. 

 coast of South Georgia; in about 54°36'S., 37°02'W. 

 It was charted by DI personnel in 1930 and named
