Totten Glacier is a large glacier draining a major portion of the East Antarctic Ice Sheet, through the Budd Coast of Wilkes Land in the Australian Antarctic Territory. The catchment drained by the glacier is estimated at 538,000 km2, extending approximately 1100 km into the interior and holds the potential to raise sea level by at least 3.5 m. Totten drains northeastward from the continental ice but turns northwestward at the coast where it terminates in a prominent tongue close east of Cape Waldron. It was first delineated from aerial photographs taken by USN Operation Highjump (1946–47), and named by Advisory Committee on Antarctic Names (US-ACAN) for George M. Totten, midshipman on the USS Vincennes of the United States Exploring Expedition (1838–42), who assisted Lt. Charles Wilkes with correction of the survey data obtained by the expedition.
