The Byvågåsane Peaks (69°25′S 39°48′E) are three low aligned rock peaks which surmount the east shore of Byvågen Bay on the east side of Lutzow-Holm Bay. They were mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37 and named Byvågåsane (the town bay peaks) in association with Byvågen Bay.^[1]
