GEOGRAPHIC NAMES OF ANTARCTICA 



THORNE, MOUNT: peak in the Will Hays Mtns. 

 of the Queen Maud Range, standing about 7 mi. 

 NW. of Mt. Goodale on the W. side of Robert Scott 

 Gl. and rising to about 6,000 ft. in el.; in about 

 85°56'S., 155°45'W. Disc, by the ByrdAE, 1928-30, 

 on the South Polar Flight of Nov. 28-29, and 

 mapped by the Southern Sledging Party of the 

 ByrdAE, 1933-35. Named for George A. Thorne, 

 topographer and dog driver of the Geological Party 

 of the ByrdAE, 1928-30, which visited this region. 



Thorne Glacier: see Robert Scott Glacier. 



Thorold Nielsen, Mount; Thorold Nilsen, Mount; 

 Thorvold Nilsen, Mount: see Thorvald Nilsen 

 Mountains. 



THORSHAVN BAY: an indentation about 15 mi. 

 wide in the edge of Amery Ice Shelf between Cape 

 Thomas and Cape Child in the S. part of Mac- 

 Kenzie Bay, along Lars Christensen Coast; in 

 about 68°45'S., 71°15'E. The Norwegian whale 

 catcher Torlyn reached Thorshavn Bay on Feb. 

 13, 1931. Named for the Norwegian motor tanker 

 Thorshavn from which Lars Christensen person- 

 ally directed exploration in 1930-31, 1932-33, 

 1933-34, and 1936-37. 



THORVALD NILSEN MOUNTAINS: mountain 

 massif of the Queen Maud Range, about 13,000 

 ft. in el., standing between the upper reaches of 

 Robert Scott and Amundsen Glaciers; in about 

 86°20'S., 158°00'W. Disc, by a Nor. exp. under 

 Amundsen, in 1911, and named for Capt. Thorvald 

 Nilsen, commander of the exp. ship Fram. Not 

 adopted: Mount Nilsen, Mount Thorold Nielson, 

 Mount Thorold Nilsen, Mount Thorvold Nilsen. 



THREE BROTHERS: three mountain peaks 

 aligned in a N.-S. direction, about 4 mi. W. of the 

 head of Cumberland West Bay, in the central part 

 of South Georgia; in 54°16'S., 36°48'W. Probably 

 named by DI personnel following their surveys of 

 South Georgia in 1926-30. Not adopted: The 

 Three Brothers. 



THREE BROTHERS HILL: conspicuous hill 

 about 700 ft. in el., which is the remnant neck of 

 an extinct volcano, situated at the S. side of Potter 

 Cove, King George I., in the South Shetland Is.; 

 in 62°14'S., 58°40'W. The name seems to have 

 been first used by the Scottish geologist David 

 Ferguson in a 1921 report based upon his in- 

 vestigations of King George I. in 1913-14, but may 

 reflect an earlier naming by whalers. The name 

 may be suggestive of the summit, which resembles 

 the knuckles of a firmly clenched fist. 



THREE LAKES VALLEY: low valley, contain- 

 ing three freshwater lakes, extending from the 

 vicinity of Elephant Flats northward to Stygian 

 Cove on Signy I., South Orkney Is.; in 60°42'S., 

 45°37'W. Surveyed and given this descriptive 

 name by the FIDS in 1947. 



THREE LITTLE PIGS: three islets about 0.5 

 mi. NW. of Winter I., in the Argentine Is., off the 

 W. coast of Palmer Pen.; in 65°15'S., 64n7'W. 

 Charted and named in 1935 by the BGLE under 

 Rymill. Not adopted: The Three Little Pigs. 



Three Point Island: see Jomfruene Island. 



THREE SISTERS POINT: point marked by three 

 conspicuous boulders about 20 ft. in el., situated 

 on the S. side of King George I. about 1 mi. NE. 

 of Penguin I., in the South Shetland Is.; in 

 62°03'S., 57°54'W. The point was charted and 

 named during 1937 by DI personnel on the Dis- 

 covery II. 



Three Slice Island: see Three Slice Nunatak. 



THREE SLICE NUNATAK: conspicuous 

 nunatak about 1,650 ft. in el., marking the low, 

 ice-covered NE. extremity of Joerg Pen., on the 

 E. coast of Palmer Pen.; in 68°02'S., 64°57'W. This 

 distinctive landmark, in the form of a serrated 

 NE.-SW. ridge about 2 mi. long, is snow covered, 

 except for the three almost vertical rock faces 

 which suggest its name. Disc, by members of East 

 Base of the USAS who surveyed this area on land 

 and from the air in 1940. Not adopted: Three 

 Slice Island. 



THULE ISLAND: westernmost island of South- 

 ern Thule, a group of three small islands at the 

 S. end of the South Sandwich Is.; in 59°27'S., 

 27°19'W. Southern Thule was disc, and named by 

 Capt. James Cook in 1775. The westernmost island 

 was named Thule Island by Adm. Thaddeus Bell- 

 ingshausen, who made an accurate sketch of these 

 islands in 1820. Not adopted: Morrel Island, Mor- 

 rell Island, Southern Thule Island. 



THULE ISLETS : group of islets and rocks lying 

 about 0.25 mi. SW. of Balin Pt. in the NW. part 

 of Borge Bay, Signy I., South Orkney Is.; in 

 60°42'S., 45°37'W. The name Thule Rocks was 

 used as early as 1916, and appears to refer at least 

 in part to this group. The Thule, one of the first 

 floating factories to flense whales at sea, belonged 

 to the Thule Whaling Co. of Oslo. It operated 

 in the South Orkney Is. in 1912-13 and 1913-14 

 and anchored on the E. side of Signy I. during 

 January 1913. The altered form of the name was 

 recommended by the Br-APC following a survey
