Johnsonufsa is the name of nunataks in Heimefrontfjella the East Antarctic Queen Maud Lands , located in the northeastern part of the Kottasberge in the ice between the Arntzenrustene and Lütkennupen be located. The nunatak was identified on an oblique aerial photograph taken during the Norwegian-British-Swedish Antarctic Expedition 1949-52 . During the first visit to the Kottas Mountains by British surveyors and geologists in the 1960s, no nunatak could be found at this point; on a map in the geological report from 1972 only crevasses are shown at the point. On the official map published in Oslo in 1988, the name Johnsonufsa is reproduced, but without the brown rock signature for Nunataks and in a thinner font. On the most detailed map of the region to date on a scale of 1: 25,000, which was published in 2004, there is also no nunatak recorded in the icefall between Lütkennupen and Arntzenrusten, which is why it can be assumed that the dark crevasses recognizable on modern satellite images were probably misinterpreted as rock areas in 1969.
Scientists at the Norwegian Polar Institute named Johsonufsa in 1969 after the brothers Anton Gisle Johnson (1893-1967) and Gunnar Johnson (1895-1957), both doctors and leaders in the resistance movement against the German occupation of Norway in World War II .
