COMPOSITE GAZETTEER OF ANTARCTICA

rising to 665 m on George VI Sound E of Mars Glacier, E Alexander Island, were photographed from the air by Ellsworth, 23 November 1935, and roughly mapped from air photographs (Joerg, 1937, map facing p.444); roughly surveyed from the ground by BGLE in October 1936 (Stephenson, 1940, map facing p.232); seen from the air by USAS in 1940-41, when the name Two Step Mountains was applied descriptively to an ill-defined feature in c.71°50'S 68°50'W (USAAF chart [LR-74], 1942); further photographed from the air by RARE in 1947, when the name Table Mountain was applied to the coastal feature defined above (Ronne, 1945, photograph p.18). Following resurvey by FIDS from "Stonington Island" in 1949, the name Two Step Cliffs was applied to the coastal feature ([in 71°54'S 68°13'W] APC, 1955, p.21; USHO chart 6638, 1956; [co-ordinates corrected] DOS 610 sheet W 71 68, 1960; APC, 1977, p.33). Skaly Tu-Step-Klifs (Soviet Union. MMF chart, 1961).

The eastern face of a flat-topped sedimentary mountain, 680 m, immediately E of Mars Glacier on the E coast of Alexander Island. First seen from the air by Lincoln Ellsworth on Nov. 23, 1935, and mapped from photos obtained on that flight by W.L.G. Joerg. Roughly surveyed from the ground in 1936 by the BGLE and in 1940-41 by the USAS, who used the names "Two Step Mountains" and "Table Mountain" for this feature. The name Two Step Cliffs derives from the name used by USAS, and was suggested by FIDS following surveys in 1949 as being particularly descriptive of this feature.
