GEOGRAPHIC NAMES OF ANTARCTICA 



in the E. part of Alexander I Island-. Despite its 

 height, it is best described as a foothill of the 

 Douglas Range, from which it is separated by 

 Toynbee Gl.; in 69°45'S., 69°29'W. First photo- 

 graphed from the air in 1936 by the BGLE. Sur- 

 veyed from the ground in 1948 by the FIDS and 

 named by them for Cecil E. Tilley, prof, of miner- 

 alogy and petrology at Cambridge University. 



TILLEY NUNATAK: bold outcrop about 300 ft. 

 in el., lying at the edge of the ice cliffs on Mac- 

 Robertson Coast; in about 67°24'S., 60°07'E. Disc, 

 in February 1936 by DI personnel on the William 

 Scoresby and named by them for Prof. C. E. Tilley, 

 who studied the rock specimens brought back by 

 the expedition. Not adopted: Nabbodden [Nor- 

 wegian] . 



TILT ROCK: isolated rock mass, about 2,200 ft. 

 in el., which rises 2 mi. inland from the ice shelf 

 of George VI Sound and stands 2 mi. NE. of Block 

 Mtn., with which it forms the S. limit of Sedgwick 

 GL, on the E. side of Alexander I Island; in 

 70°27'S., 68°44'W. First photographed from the 

 air on Nov. 23, 1935 by Lincoln Ellsworth, and later 

 mapped from these photographs by W. L. G. Joerg. 

 Roughly surveyed from the ground in 1936 by the 

 BGLE under Rymill, and resurveyed in 1948-49 

 by the FIDS. So named by FIDS because of the 

 tilted appearance of the whole mass. Not adopted : 

 Pyramid Point. 



TINSEL DOME: small, ice-covered hill about 

 2,300 ft. in el., standing between Aureole Hills and 

 the mouth of West Russell Gl., on the NW. side of 

 Louis Philippe Pen.; in 63°43'S., 58°52'W. Charted 

 in 1948 by the FIDS who gave this descriptive 

 name. 



TIOGA HILL: rounded summit, about 950 ft. in 

 el., standing at the W. side of the head of McLeod 

 Gl. on Signy I., South Orkney Is.; in 60°44'S., 

 45°39'W. The hill is the highest point on the 

 island. Surveyed in 1947 by the FIDS. Named by 

 the Br-APC in 1954 after the Tioga, owned by 

 Messrs. Christensen and Co., Corral, Chile, which 

 was one of the first floating factories to flense 

 whales at sea. It was wrecked at nearby Port 

 Jebsen during a gale on Feb. 4, 1913. 



TITAN NUNATAK: broad, rather flat-topped 

 nunatak, about 1,500 ft. in el., standing between 

 Coal Nunatak and Tethys Nunataks in the SE. 

 corner of Alexander I Island; in 72°09'S., 68°43'W. 

 This nunatak was first photographed from the air 

 by Lincoln Ellsworth on Nov. 23, 1935. Observ- 

 ing this feature from the NW. (the direction from 

 which Ellsworth photographed this nunatak) only 

 the summit protrudes above the coastal ice, and 



it was uncertain at that time whether this was 

 a peak on Alexander I Island or an island in George 

 VI Sound. Its true nature was determined by the 

 FIDS who visited and surveyed this nunatak in 

 1949. Named by FIDS for its association with 

 nearby Saturn Glacier; Titan being one of the 

 satellites of Saturn. 



TOE, THE: point marking the S. side of the en- 

 trance to Harmony Cove on the W. side of Nelson 

 I., in the South Shetland Is.; in 62°20'S., 59°10'W. 

 This descriptive name seems first to appear on a 

 chart based upon a 1935 survey by DI personnel 

 on the Discovery II. 



TOFE GLACIER: glacier immediately S. of 

 Sandefjord Bay, descending between high, rocky 

 cliffs to the W. coast of Peter I Island; in about 

 68°51'S., 90°44'W. Disc, in 1927 by a Nor. exp. 

 in the Odd I and named for Eyvind Tofte, leader 

 of the expedition. 



Tokroningen: see Kroner Lake. 



TOLLEY, MOUNT: peak in the Allegheny Mtns., 

 in the E. part of the Edsel Ford Ranges in Marie 

 Byrd Land; in about 77°17'S., 143°00'W. Disc, 

 on aerial flights from the West Base of the USAS, 

 in 1940, and named for Pres. William Pearson 

 Tolley, of Allegheny College, Pennsylvania. Not 

 adopted: Mount Tolly. 



Tolly, Mount: see Tolley, Mount. 



TOMBSTONE HILL: hill about 170 ft. in el. 

 on the N. side of the harbor of Port Lockroy, 

 Wiencke I., about 0.25 mi. E. of Damoy Pt., in the 

 Palmer Arch; in 64°49'S., 63°32'W. Disc, by the 

 FrAE, 1903-5, under Charcot, who surveyed Port 

 Lockroy. Named by the FIDS in 1944. The name 

 is descriptive of some rocks on the top of the hill. 



TONKIN ISLAND: snow-capped island about 4 

 mi. long in a N.-S. direction, marked by ice-free 

 peaks at each end, about 11 mi. SE. of Cape 

 Choyce, off the E. coast of Palmer Pen.; in 67°49'S., 

 65°03'W. The island was disc, and photographed 

 from the air by the USAS in 1940. It was charted 

 by the FIDS in 1947, and named for J. E. Tonkin, 

 member of the FIDS at the Stonington Island 

 base. Not adopted: Lewis Island. 



Tonsberg Fiord: see T0nsberg Fjord. 



T0NSBERG FJORD: small recession in the W. 

 end of the bight between Penguin Pt. and Con- 

 ception Pt., on the N. coast of Coronation I., in the 

 South Orkney Is.; in 60°32'S., 45°55'W. Charted 

 in 1912-13 by Petter S0rlle, Norwegian whaling 

 captain. Probably named for the T0nsberg
