About this map

The volcanic backbone of the Aleutian Islands dominates this mid-century survey of Umnak, featuring the massive Okmok Caldera and the towering peak of Mt Vsevidof. To the northeast, the presence of an Air Force Base and a Military Reservation Boundary reflects the post-war strategic importance of the archipelago, including a Landing Area and a marked Camp.
