1951 Map of Unimak

USGS Topo · Published 1968

About this map

The massive geological features of the Aleutian Islands dominate this survey, centered on the dramatic profile of Unimak Island. The terrain is defined by the massive Fisher Caldera and volcanic summits like Pogromni Volcano and Westdahl Peak. At the coast, the Lighthouse at Cape Sarichef and the station at Scotch Cap indicate the critical role this landmass plays in Bering Sea navigation. Small maritime outposts and seasonal sites are visible, including a Whaling Sta in Akutan Harbor and various landings like Sealion Pt. The map captures a landscape largely encompassed by the Aleutian Islands National Wildlife Refuge, where high-relief peaks like Eickelberg Peak rise abruptly from the Slime Bank and Unimak Bight.
