1989 Map of Unimak C-1

USGS Topo · Published 1989

About this map

The Fisher Caldera dominates the northwestern portion of this coastal survey, where the volcanic landscape meets the southern reaches of the Aleutian Islands. This 1989 edition, based on earlier aerial photography, captures the transition from the high-elevation peaks of the Aleutian Islands Wilderness down to the curved shoreline of Unimak Bight. The geography is defined by its isolation and the sharp contrast between the inland caldera and the maritime edge along Promontory Cove. A quiet point of coastal interest lies at Cape Rukavitsie on the eastern edge of the bight. As part of the Aleutians East Borough, the map illustrates a landscape governed by federal conservation boundaries and the vast waters of the Pacific Ocean, with no roads or permanent settlements recorded in this remote stretch of the archipelago.
