La Grange Nunataks (80°18′S 27°50′W / 80.300°S 27.833°W) is a scattered group of nunataks extending west for 22 nautical miles (41 km) from the mouth of Gordon Glacier, on the north side of the Shackleton Range, Antarctica. They were first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition (CTAE), and were photographed in 1967 by U.S. Navy aircraft. They were named by the UK Antarctic Place-Names Committee for Johannes J. La Grange, a South African meteorologist with the CTAE. Not: Beney Nunataks.[1]
