Its elevation is 4839 ft. It was discovered about 1992. It is about 175 km southwest of Anchorage, Alaska. It is just north of Redoubt volcano and between Redoubt and Mt Spur in the Aluetian Range.[1] [2][3]
Double Glacier Volcano[2][3] lava dome complex of Pleistocene age forms a nunatak in Double Glacier. K–Ar dating of the complex indicates that it formed 627,000 to 887,000 years ago.[4]
