Mount Discovery is a conspicuous, isolated stratovolcano, lying at the head of McMurdo Sound and east of Koettlitz Glacier, overlooking the NW portion of the Ross Ice Shelf. It forms the center of a three-armed mass of which Brown Peninsula is one extension to the north; Minna Bluff is a second to the east; the third is Mount Morning to the west. Discovered by the British National Antarctic Expedition (1901–04) and named for their expedition ship Discovery.
