COMPOSITE GAZETTEER OF ANTARCTICA

(1977), an area of fissures in Brunt Ice Front ENE of Halley, was the feature roughly charted by BITAE in January 1915 and called Allan McDonald Glacier after Allan McDonald, of the British Association of Magallanes, Punta Arenas, who was mainly responsible for raising funds (in 3 days) for sending the British relief expedition in Emma on the third abortive attempt, in July 1916, to rescue the Endurance party on Elephant Island (Shackleton, 1919, p.216) (Worsley, chart 4, 1914-15; Shackleton, 1919, end map; USHO, 1943, p.356).

The feature was renamed McDonald Ice Rumples, the generic term being defined as "a locally grounded area of ice shelf which is overridden by an ice sheet" (Armstrong and others, 1977, p.502) (APC, 1960, p.5; Ardus, 1965, p.18; Thomas, 1973, map p.6). Lednik MakDonalda (Soviet Union. MMF chart, 1961).

A severely disturbed area in the Brunt Ice Shelf, which is assumed to be aground and pushed upward in this vicinity. It covers an area 3 by 2 miles. In 1957 the maximum elevation above the general surface of the ice shelf was about 18 meters, a few hundred meters from the ice front. The Royal Society IGY expeditions occupied a base nearby (1955-59) and were familiar with this feature. It has now been identified with "Allan McDonald Glacier" reported by Shackleton's expediton in January 1915. For the sake of historical continuity the UK-APC has given the name McDonald to these ice rumples. Allan McDonald of the British Association of Magallanes at Punta Arenas was chiefly responsible for raising funds for sending the Emma on the third attempt, in July 1916, to rescue the 22 men of the Endurance left on Elephant Island.
