About this map

Volcanic formations and military land use define this 1951 survey of the Aleutian landscape, dominated by the massive Okmok Caldera and the towering peaks of Mt Vsevidof and Mt Recheshnoi. The northeastern end of the island is marked by the Fort Glenn Military Reservation Boundary, providing a clear record of mid-century strategic presence in the Pacific. Unique geothermal and hydrological features are named along the coast, including the Weeping Wall, Hot Springs Cove, and Boiling Pinnacles.

Maritime and local history is visible in the naming of small coastal indentations such as Cemetery Cove and Stepanof Cove within Inanudak Bay. The map also captures the isolated outposts of the Aleutian Islands chain, including the distinct Bogoslof Island and Fire Island to the north. These details provide an essential view of the island's geography before later geological shifts and administrative changes in the region.
