|location||Mac Robertson Land , East Antarctica|
Aerial photographs of this and the neighboring Nunatakker were taken during the US operation Highjump (1946–1947) and in 1957 as part of the Australian National Antarctic Research Expeditions (ANARE). Participants of a Soviet Antarctic expedition visited them in 1965. The same applies to an ANARE team in 1969 whose actual target area was the Prince Charles Mountains . The Nunatak described here is named after Christopher R. Bain, a member of this team and also a weather observer at Mawson Station in the same year .
