GEOGRAPHIC NAMES OF ANTARCTICA 



Seward Nunataks: see Seward Mountains. 



SEYMOUR ISLAND: island about 10 mi. long 

 and about 5 mi. wide at its greatest breadth, lying 

 1 mi. NE. of Snow Hill I. and S. of the NE. end of 

 Palmer Pen.; in 64° IT'S., 56°45'W. The NE. end 

 of this feature was sighted by a Br. exp. under 

 Ross, Jan. 6, 1843, and named Cape Seymour after 

 R. Adm. George Francis Seymour. Its insular 

 nature was determined by Capt. C. A. Larsen in 

 1892-93 and the name Seymour has since been 

 extended to the entire island. 



SHACKLETON GLACIER: major glacier, about 

 12 mi. wide at its mouth and perhaps 80 to 100 mi. 

 long, descending from the polar plateau, approxi- 

 mately along the 175th meridian west longitude, to 

 the head of Ross Ice Shelf. Disc, by the USAS on 

 the flight of February 29-March 1, 1940. Named 

 by the US-SCAN for Sir Ernest H. Shackleton, fa- 

 mous British Antarctic explorer. Not adopted: 

 Wade Glacier. 



SHACKLETON ICE SHELF: an extensive ice 

 shelf fronting for about 105 mi. on the Queen Mary 

 Coast from about 94°55'E. to about 99°25'E., and 

 projecting seaward in the west-central portion for 

 an undetermined distance of more than 60 miles. 

 The extreme W. portion, namely the 20-mile section 

 fronting on the coast between Junction Corner and 

 Roscoe Gl., was determined from USN Op. Hjp. 

 aerial photographs taken in February to extend 

 seaward for about 20 mi. to a point close S. of 

 Bigelow Rock. The E. end was determined from 

 these photographs to extend seaward for about 33 

 mi. from the 20-mile section between Davis Pen. 

 and Delay Point. Additional study is required to 

 determine whether the large tongue opposite Den- 

 man Gl. should be included as forming the E. end 

 of the ice shelf, as small open water areas (dead 

 water) lie within the portion of the tongue close 

 NNE. of Jones Ridge, a prominent nunatak stand- 

 ing above the lower reaches of Denman Glacier. 

 The existence of this ice shelf was first made known 

 by the USEE under Wilkes, who explored along its 

 E. and NE. front in the Vincennes in February 

 1840. It was named by the.AAE under Mawson, 

 1911-14, for Sir Ernest Shackleton. Not adopted: 

 Shackleton Shelf, Shackleton Shelf Ice, Termina- 

 tion Barriere Eis [German] . 



SHACKLETON INLET: a re-entrant about 10 

 mi. wide, with Nimrod Gl. at its head, lying between 

 Cape Wilson and Cape Lyttelton, at the W. side of 

 Ross Ice Shelf; in about 82°22'S., 163°00'E. Disc, 

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

 Lt. (later Sir) Ernest Shackleton, RNR, who, with 

 Dr. Edward A. Wilson, accompanied Scott on his 

 attempted journey to the pole. 



SHACKLETON PEAK: mountain with perpen- 

 dicular cliffs facing W., about 4,800 ft. in el., stand- 

 ing about 2 mi. E. of Chaigneau Peak on the W. 

 coast of Palmer Pen.; in 65°13'S., 63°56'W. Disc. 

 by the FrAE, 1908-10, under Charcot, and named 

 by him for Sir Ernest Shackleton. 



Shackleton Shelf Ice: see Shackleton Ice Shelf. 



SHAGNASTY ISLET: small, rocky ice-free islet 

 lying about 0.4 mi. W. of Lenton Pt. in the N. part 

 of Clowes Bay, close off the S. coast of Signy I., 

 South Orkney Is.; in 60°44'S., 45°38'W. Roughly 

 charted in 1933 by DI personnel, and surveyed in 

 1947 by the FIDS. The name, applied by FIDS, 

 arose from the unpleasant state of the islet due to 

 its occupation by a large colony of blue-eyed shags 

 (Phalacrocorax atriceps) . 



SHAG ROCK: rock about 0.1 mi. ESE. of Cliff 

 Islet and some 8 mi. W. of Ferin Head, off the W. 

 coast of Palmer Pen.; in 66°00'S., 65°42'W. 

 Charted and named by the BGLE, 1934-37, under 

 Rymill. 



SHAG ROCKS: group of insular rocks about 240 

 ft. in el., lying some 115 mi. WNW. of South Geor- 

 gia; in about 53°33'S., 42°02'W. Shag Rocks, prob- 

 ably so named because shags and other sea birds 

 frequent them, were knov/n to sealers prior to 1823 

 and probably are identical with the "Aurora 

 Islands" reported in this vicinity by the ship 

 Aurora in 1762. They were charted by DI person- 

 nel on the William Scoresby in 1927. 



SHALLOW BAY: bay about 10 mi. wide formed 

 by a recession of limited depth in the ice cliffs in 

 the E. part of Mac-Robertson Coast; in about 

 67°48'S., 67°36'E. Disc, by the BANZARE under 

 Mawson on Feb. 12 or 13, 1931 and so named be- 

 cause it formed only a shallow indentation in the 

 coast line. ( 



SHAMBLES GLACIER: steep glacier with very 

 prominent hummocks and crevasses, about 6 mi. 

 v/ide and of undetermined length, flowing SE. be- 

 tween Mt. Bouvier and Mt. Mangin to Stonehouse 

 Bay on the E. side of Adelaide I.; in 67°20'S., 

 68°15'W. The lower reaches of the glacier were 

 first sighted and surveyed in 1909 by the FrAE 

 under Charcot, and resurveyed in 1948 by the 

 FIDS. So named by FIDS because of the very 

 broken nature of its surface. 



SHANNON POINT: point marking the W. side 

 of the entrance to Esbensen Bay, at the SE. end of 

 South Georgia; in 54°52'S., 36°00'W. The point 

 was charted in 1930 by DI personnel on the William 

 Scoresby. Named for Lt. Cdr. R. L. V. Shannon,
