 D'Urville. Charted by the SwedAE, 1901-4, under 

 Nordenskjdld. Not adopted: Orleans Channel, 

 Orleans Inlet. 



Orleans Inlet: see Orleans Channel. 



ORNEN ROCKS : group of rocks, some of which 

 are above water, about 1 mi. NNE. of Cape Melville, 

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

 62°G0'S., 57°32'W. Named after the Norwegian 

 whaler Omen which went aground there about 

 1908 or 1909. Not adopted: Rochers de I'Orn 

 [French] . 



ORVILLE ESCARPMENT: a southeast-facing es- 

 carpment along the NW. edge of Edith Ronne Land, 

 extending from the junction of Filchner Ice Shelf 

 and Palmer Pen.; in about 75°10'S., 63°00'W., south- 

 westward for about 200 mi. to about 77°30'S., 

 71°30'W. Disc, by the RARE, 1947-48, under 

 Ronne, who named this feature for Capt. Howard 

 T. Orville, USN, Head of the Naval Aerological Serv- 

 ice, who was largely responsible for the formulation 

 of the meteorological program of the expedition. 



ORWELL BIGHT: body of water lying S. of the 

 eastern half of Coronation I., bounded on the west 

 by Signy I. and on the east by the Robertson Is., in 

 the South Orkney Is.; in 60°44'S., 45°23'W. The 

 general nature of this bight was first delineated by 

 Petter S0rlle, Norwegian whaling captain who 

 mapped this area in 1912-13. It was surveyed by 

 DI personnel in 1933 and by the FIDS in 1948-49. 

 Named by the Br-APC after the Norwegian trans- 

 port Orwell, the second ship of that name belong- 

 ing to the T0nsberg Hvalfangeri, which anchored 

 in Borge Bay, Signy I., on the W. side of this bight 

 in the seasons 1925-26 to 1929-30. 



ORWELL GLACIER: small glacier, less than 0.5 

 mi. long, which descends steeply from the S. slopes 

 of Snow Hill and terminates in 60 foot ice cliffs 

 along the S. margin of Elephant Flats in the E. 

 part of Signy I., South Orkney Is.; in 60°43'S., 

 45°38'W. Surveyed by DI personnel in 1927, and 

 named by them after the Norwegian transport 

 Orwell, which anchored in Borge Bay, Signy I., 

 throughout the seasons 1925-26 to 1929-30. The 

 glacier was resurveyed by the FIDS in 1947. 



OSCAR II COAST: that portion of the E. coast 

 of Palmer Pen., extending from Cape Fairweather, 

 in 65°00'S., 61°05'W., to Cape Alexander, in 

 66°44'S., 62°37'W. Named in 1893 by Capt. C. A. 

 Larsen for King Oscar II of Sweden. Not adopted : 



King Oscar II Coast, King Oscar II Land, Konig 

 Oskar II Land [German], Kong Oscar II Kiiste, 

 Terre du Roi Oscar [French] . 



Oscar Island: see Inexpressible Island. 



OSCAR ISLAND: the more northerly of two 

 small islands lying close to the ice cliffs about 20 

 mi. W. of Cape Washington, along the coast of 

 Victoria Land; in about 74°43'S., 164°20'E. Disc, 

 by the BrAE, 1898-1900, under C. E. Borchgrevink, 

 who named it for King Oscar of Norway and Swe- 

 den. Not adopted: Inexpressible Island (q.v.). 



Oscar Wisting, Mount: see Wisting, Mount. 



OSMIC HILL: conspicuous rounded hill which 

 rises abruptly from the surrounding plain to about 

 1,000 ft. in el., marking the N. limit of an undulat- 

 ing ridge of hills on the W. side of Moraine Fjord, 

 South Georgia; in 54°18'S., 36°30'W. Roughly 

 surveyed by the SwedAE, 1901-4, under Norden- 

 skjold. Named by the FIDS following their sketch 

 survey in 1951. The name is one in a group in the 

 vicinity of Discovery Pt., derived from the chemical 

 fixatives used there in biological work by the FIDS. 



OSTERRIETH MOUNTAINS: mountain range 

 culminating in Mt. Frangais, about 9,100 ft. in el., 

 and extending in a NE.-SW. direction along the 

 SE. coast of Anvers I., in the Palmer Arch.; center- 

 ing in about 64°37'S., 63°25'W. Disc, by the 

 BelgAE, 1897-99, under De Gerlache, and named 

 by him for Mme. Ernest Osterrieth, a patron of 

 the expedition. Not adopted: Osterrieth Moun- 

 tains. 



Osterrieth Mountains: see Osterrieth Mountains. 



O'SULLIVAN PEAK: ice-covered peak about 

 5,800 ft. in el. which forms the highest point and is 

 near the S. end of a N.-S. trending ice-covered 

 ridge, standing about 11 mi. W. of the head of the 

 N. arm of Odom Inlet, on the E. coast of Palmer 

 Pen.; in 71°26'S., 62°06'W. This peak was photo- 

 graphed from the air by US AS in December 1940, 

 and was probably seen by the expedition's ground 

 party that explored this coast. First charted by a 

 joint party consisting of members of the RARE 

 and the FIDS in 1947. Named by the FIDS for 

 T. P. O'Sullivan, a member of the FIDS at the Hope 

 Bay base in 1946-47. 



OUTER ISLET: islet fringed by submerged 

 rocks, about 0.3 mi. E. of Berntsen Pt., the S. en- 

 trance point to Borge Bay, off the E. side of Signy 

 I., in the South Orkney Is.; in 60°43'S., 45°35'W. 

 Charted in 1933 by DI personnel on the Discovery 

 II, and so named because of its position close out- 

 side the entrance to Borge Bay.
