COMPOSITE GAZETTEER OF ANTARCTICA

properly an ice rise reaching a height of 975m and dividing Ronne Ice Shelf from Filchner Ice Shelf, was first seen from the air by RARE, 12 December 1947, but was not distinguished from ice shelf (Ronne, 1949, p.227); reported to be an island, following a US reconnaissance flight from "Ellsworth Station" in October 1957; roughly mapped from the ground by a field party from that station in 1957-58 and called Hubley Island, after Dr. Richard Charles Hubley (1930-57), US glaciologist and Co-ordinator of Glaciological Activities in the Northern Hemisphere for the IGY, who died on McCall Glacier, Brooks Range, Alaska (Thiel and others, 1958, p.10 and Fig. 9); named Berkner Island after Dr. Lloyd Viel Berkner (Rear-Adm., USNR) (1905-1967); American physicist, university administrator and US Government adviser; radio engineer, First Byrd Antarctic Expedition, 1928-30; President, International Council of Scientific Unions, 1955-58; joint initiator with S. Chapman (Chapman Point, q.v.) of the IGY (USBGN, 1960, p.1; Ronne, 1961, map Front.; APC, 1962, p.5; DOS (Misc.) 135 Antarctica sheet, 1963). Berkner Bank, referring to the submarine feature on which Berkner Island and Henry Ice Rise (q.v.) are grounded ice features (Behrendt, 1962b, p.19). Ostrov Berkner (Soviet Union. MMF chart, 1961). Vozvyshennost' Berkner (Soviet Union. AA, 1966, Pl. 24). Isla Berkner (Pierrou, 1970, p.199). The island was further delineated from US LANDSAT imagery of January 1973 (BAS sheet Misc. 2, 1981). Berkner-Insel (Germany. IAG map, 1984).

A high and completely ice-covered island about 200 mi long and 85 mi wide. This large feature rises to 975 m and separates Ronne Ice Shelf from Filchner Ice Shelf. Discovered by members of the US-IGY party at Ellsworth Station, under the leadership of Capt. Finn Ronne, USNR, during the 1957-58 season. Named by US-ACAN for American physicist Lloyd V. Berkner, engineer with the Byrd Antarctic Expedition, 1928-30.

A cigar shaped lake just to the north of Blundell Peak in the Larsemann Hills. A field campsite was set up at this lake by members of the 1986-87 ANARE Field Party to allow biological work on a pair of lakes named "Jack" and "Jill" after the nursery rhyme characters. There is an associated hill called Tumbledown Hill.
