Features

Lava Tongue Pass

78°14′00″S 162°41′00″E / 78.2333333°S 162.6833333°E / -78.2333333; 162.6833333 A prominent north-south gully at 1,850 metres (6,070 ft) high bisecting Radian Ridge. Named descriptively by New Zealand Geographic Board (NZGB) (1994) following work in the area by a NZGS field party, 1977-78, for a lava flow that fills the pass.^[2]

Anne Hill

78°14′00″S 162°43′00″E / 78.2333333°S 162.7166667°E / -78.2333333; 162.7166667 The most prominent hill on Radian Ridge. It rises to 2,079 metres (6,821 ft) high at the east side of Lava Tongue Pass. Named after Anne C. Wright (later Anne Wright-Grassham), a geologist with the New Zealand Geological Survey field party in this area, 1977-78; geologist with United States Antarctic Research Program (United States ArmyRP) field parties, 1982-83, 1983-84, and 1985-86 seasons, with work at Ross Island, Minna Bluff, Mount Discovery, Mount Morning, and Mason Spur.^[3]

Boom Basin

78°14′00″S 162°48′00″E / 78.2333333°S 162.8°E / -78.2333333; 162.8 A small basin on the north side of Radian Ridge, immediately west of the confluence of Pipecleaner Glacier and Radian Glacier, Royal Society Range. A loud explosive boom was heard by members of a NZGS field party working in the area on December 3, 1977. They suggested the name. The source of the noise remained a mystery.^[4]

Named descriptively by New Zealand Geographic Board (NZGB) (1994) following work in the area by a NZGS field party, 1977-78, from the horseshoe shape of the crater.^[5]
