About this map

Glacial peaks and volcanic vents dominate the northern Aleutian Islands in this mid-century survey of Umnak. The landscape is defined by the massive Okmok Caldera and the towering heights of Mt Vsevidof and Mt Recheshnoi. These landforms dictate the location of human activity, with a Landing Area and Camp situated near the island's northeast coast. Coastal life is centered around deep inlets like Inanudak Bay and Amos Bay, while geothermal activity is indicated by Geyser Bight and Hot Springs Cove.

Maritime history is evident in the naming of remote landmarks such as Cemetery Cove and The Pillars. To the north, the isolated Bogoslof Island is noted as the Bogoslof National Wildlife Refuge, marking it as a protected environment during the early 1950s. The map illustrates a transition from the volcanic north to the high, snow-clad mountains of the south, showing the rugged reality of the Bering Sea frontier.
