GEOGRAPHIC NAMES OF ANTARCTICA 



OLD MANS HEAD: dark headland marking the 

 S. side of the entrance to Wiist Inlet, on the E. 

 coast of Palmer Pen.; in 72°22'S., 60°45'W. Disc, 

 and photographed from the air in December 1940 

 by members of the USAS. During 1947 the head- 

 land was photographed from the air by the RARE, 

 who in conjunction with the FIDS charted it from 

 the ground. This descriptive name was given by 

 the FIDS. 



Ole Engelstad, Mount: see Engelstad, Mount; 

 Wilhelm Christophersen, Mount. 



OLIPHANT ISLETS: group of small ice-free 

 islets and rocks lying S. of Gourlay Pen., the SE. 

 extremity of Signy I., South Orkney Is.; in 60°45'S., 

 45°36'W. Dove Channel extends through this 

 group in a general E.-W. direction. The group 

 was roughly charted in 1912-13 by Petter S0rlle, 

 Norwegian whaling captain, and again in 1933 by 

 DI personnel. Surveyed in 1947 by the FIDS and 

 named by them for Prof. Marcus L. E. Oliphant, 

 then prof, of physics, Birmingham Univ.; later Dir. 

 of the Research School of Physical Sciences, 

 Australian National Univ., who gave assistance to 

 the FIDS in obtaining equipment. 



OLIVINE POINT: the southern end of the low- 

 lying peninsula which forms the E. limit of Iceberg 

 Bay on the S. coast of Coronation I., South Orkney 

 Is.; in 60°41'S., 45°29'W. Surveyed by the FIDS 

 in 1948-49, and so named by them because the 

 mineral olivine occurs in the igneous dikes inter- 

 secting the peninsula just N. of the point. 



OLSTAD GLACIER: heavily crevassed glacier 

 decending to the W. side of Peter I Island, about 

 2.5 mi. S. of Tofte GL; in about 68 53'S., 90°43'W. 

 Peter I Island was circumnavigated by the Norwe- 

 gian whale catcher Odd I in January 1927, and 

 charted by the Norvegia in February 1929. They 

 named the glacier for Ola Olstad, Norwegian biolo- 

 gist who, transported by various whaling ships, 

 conducted research in South Georgia, South Shet- 

 land Is., and the Palmer Archipelago. Not 

 adopted: Olstads Glacier. 



OMEGA ISLAND: island, about 2 mi. long, which 

 lies immediately S. of Eta I. in the Melchior Is., 

 Palmer Arch.; in 64"20'S., 62°56'W. This island, 

 the largest feature in the SE. part of .the Melchior 

 Is., is part of what was called "He Melchior" by the 

 FrAE under Charcot, 1903-5, but the name Mel- 

 chior now applies for the whole island group. 

 Omega Island was roughly surveyed by DI person- 

 nel in 1927. The name Omega, derived from the 

 last letter of the Greek alphabet, appears to have 

 been first used on a 1946 Argentine govt, chart fol- 

 lowing surveys of the Melchior Is. by Arg. expedi- 



tions in 1942 and 1943. Not adopted: Isla Sobral 

 [Spanish] . 



Omicron, Islas: see Omicron Islets. 



OMICRON ISLETS: group of small islets and 

 rocks which lie close SE. of the SE. extremity of 

 Omega I. in the Melchior Is., Palmer Arch.; in 

 64°21'S., 62°55'W. The name, derived from the 

 15th letter of the Greek alphabet, appears to have 

 been first used on a 1946 Argentine govt, chart 

 following surveys of these islets by Arg. expeditions 

 in 1942 and 1943. Not adopted: Islas omicron 

 [Spanish] , Islas Silveyra [Spanish] . 



OMMANNEY BAY: semi-circular bay about 2.5 

 mi. wide, lying immediately W. of Foul Pt. along 

 the N. coast of Coronation I., in the South Orkney 

 Is.; in 60°33'S., 45°34'W. Probably first sighted by 

 Capt. George Powell and Capt. Nathaniel Palmer 

 in 1821. The bay was charted in 1933 by DI per- 

 sonnel on the Discovery II, and named for Francis 

 Downes Ommanney, zoologist on the staff of the 

 Discovery Committee. 



OMMANNEY GLACIER: glacier descending to 

 Relay Bay, in the Robertson Bay area of northern 

 Victoria Land; in about 71°32'S., 169°29'E. First 

 charted by the BrAE, 1898-1900, under C. E. Borch- 

 grevink, who named it for Adm. Sir Erasmus Om- 

 manney, who had served in the Arctic Expedition 

 of 1850. Not adopted: Ommaney Glacier. 



ONGLEY ISLAND: small island lying about 3 

 mi. W. of Dee I., close off the N. side of Greenwich 

 I., in the South Shetland Is.; in about 62°25'S., 

 59°55'W. Charted in 1935 by DI personnel on the 

 Discovery II, but the name appears to have been 

 first used on a 1948 Admiralty chart based upon 

 this survey. 



OOM BAY: small bay about 2 mi. wide, lying 

 between Cape Bruce and Campbell Head along 

 Mac-Robertson Coast; in about 67°26'S., 60°47'E. 

 Disc, by the BANZARE under Mawson on Feb. 18, 

 1931, and named by him for Lt. K. Oom, one of the 

 airplane pilots of the expedition. Not adopted: 

 Uksvika [Norwegian]. 



ORGAN PIPE CLIFFS : high palisades of colum- 

 nar rock overlooking Buckley Bay for a distance of 

 10 mi. southwestward of Cape Blake, on George V 

 Coast; in about 68°25'S., 148°45'E. Disc, by the 

 AAE, 1911-14, under Mawson and so named be- 

 cause of their appearance. 



ORLEANS CHANNEL: channel about 4 mi. wide 

 extending in a NE.-SW. direction between Trinity 

 I. and the W. coast of Palmer Pen.; in 63°53'S., 

 60°35°W. This channel was possibly first seen by 



232
