It was first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. The peak was sighted from a distance in 1949 by the Falkland Islands Dependencies Survey (FIDS) and roughly positioned. It was named by the UK Antarctic Place-Names Committee for its association with nearby Saturn Glacier, Mimas being one of the satellites of the planet Saturn. The peak and surrounding area were first mapped in detail from air photos taken by the Ronne Antarctic Research Expedition 1947–48, by D. Searle of the FIDS in 1960. Note that some maps incorrectly attach the name to a subsidiary and smaller peak off the east flank of the mountain. The name is actually attached to the highest peak in the Herschel Heights range.
