COMPOSITE GAZETTEER OF ANTARCTICA

An extensive ice shelf off the coast of Queen Mary Land extending up to 170 km northwards and stretching along the coast from Junction Corner (94 degrees 45' E) to at least the Denman Glacier (99 degrees E). Recent Soviet charts show the shelf extending as far east as 105 degrees E., but there are some doubts as to whether this is one continuous ice shelf or two shelves separated by the Denman and Scott Glaciers. The eastern part of the ice shelf was sighted by the US Exploring Expedition under Wilkes in February, 1840. The western portion was explored by the Western Base Party of AAE (1911-14).

An extensive ice shelf fronting the coast of Antarctica for about 240 mi (95E to l05E), projecting seaward about 90 mi in the W portion and 40 mi in the east. The existence of this ice shelf was first made known by the USEE under Wilkes who mapped a portion of it from the Vincennes in February 1840. It was explored by the AAE under Mawson (1911-14) who named it for Sir Ernest Shackleton. The extent of the ice shelf was mapped in greater detail in 1955, using aerial photography obtained by USN Operation HighJump, 1946-47. Further mapping by the Soviet Expedition of 1956 showed the portion eastward of Scott Glacier to be a part of this ice shelf.
