 Lost Seal Stream

Lost Seal Stream () is a glacial meltwater stream, long, draining from the west margin of Commonwealth Glacier into the northeast end of Lake Fryxell, in Taylor Valley, Victoria Land, Antarctica.The name was suggested by Diane McKnight, leader of a United States Geological Survey team that studied the hydrology of streams flowing into Lake Fryxell in several seasons, 1987–94, and commemorates the encounter with a living Weddell seal.
