LeConte Glacier is a 21-mile (34 km) and 1-mile (1.6 km) glacier in the U.S. state of Alaska. It flows southwest to the head of LeConte Bay. It was named in 1887 by U.S. Navy Lieutenant-Commander Charles M. Thomas in honor of a California geologist Joseph LeConte. According to John Muir's book about indigenous peoples of the area, the Tlingits called it “Huti [sic]” which he claimed derived from a mythical bird that produced sounds of thunder when it flapped its wings.
