About this map

Unimak Island and its surrounding archipelago dominate this mid-century reconnaissance, capturing a landscape defined by active volcanism and maritime navigation. The towering Pogromni Volcano and Fisher Caldera anchor the island interior, while the Tugamak Range stretches toward the northern coastline. Maritime activity is evidenced by the Cape Sarichef Lighthouse and the Akutan Seaplane Anchorage, essential hubs for transportation in this remote corner of the Aleutian Islands.

Tracing the coastline reveals specialized industrial and logistical sites, such as the Whaling Sta on Akutan Island and a designated Landing Area near Sealion Pt. Numerous lagoons, including Peterson Lagoon and Christianson Lagoon, break the shoreline, while the vast Slime Bank extends into the Bering Sea. Small cabins represent the sparse human footprint in a region largely designated as the Aleutian Islands National Wildlife Refuge.
