abstract:Mussorgsky Peaks () are two rocky peaks rising to about 500 m lying northwest of Mount Grieg on the base of the Derocher Peninsula, a minor, ice-covered peninsula that protrudes out from the Beethoven Peninsula into the Wilkins Ice Shelf in the southwest portion of Alexander Island, Antarctica. A number of peaks in this vicinity first appear on maps by the Ronne Antarctic Research Expedition (RARE), 1947-48.
