1958 Map of Umnak

USGS Topo · Published 1958

About this map

Okmok Caldera dominates the northeastern section of Umnak Island, its massive volcanic basin defined by sharp ridges and proximity to Tulik Vol. This 1950s survey captures the island's landscape during an era of significant military presence, noted by the Air Force Base and a Military Reservation Boundary that spans the center of the island. The coastline is a complex of deep indentations and rocky features, from the sheltered Hot Springs Cove and Izhiga Cove to the sheer basalt formations of The Pillars. Topographic detail reveals the island's volcanic backbone, including the high peaks of Mt Vsevidof and Mt Recheshnoi. Rare human markers in this maritime environment include a Cemetery near Geyser Bight and a small Camp to the north, while outlying features like Bogoslof Island sit isolated in the Bering Sea.
