1951 Map of Umnak

About this map

Okmok Caldera and the towering peak of Mt Vsevidof dominate this reconnaissance survey of the Aleutian chain, recorded shortly after the Second World War. The map details a landscape shaped by active geothermal forces, specifically noting the Geyser Bight and Hot Springs Cove on the western coast. This era of the Alaskan Territory is marked by a nascent military footprint, visible in the Air Force Base and surrounding Military Reservation Boundary on the island's northeast corner. Localized maritime and coastal features such as Cemetery Cove, Steeple Point, and Inanudak Bay provide specific points of reference for researchers and maritime historians. To the west, the Islands of the Four Mountains rise from the sea, including Uliaga Island and Kagamil Island, providing a clear record of the volcanic archipelago before further modern development.
