Norwegian cartographers mapped it on the basis of aerial photographs and measurements of the Third Norwegian Antarctic Expedition (1956-1960) from 1958 to 1959. Between 1960 and 1961, Soviet scientists carried out new measurements and naming. It is named after the Soviet geologist Lev Borissowitsch Ruchin (1912–1959) from the University of Leningrad . The Advisory Committee on Antarctic Names transferred the Russian name to English in 1970.
