1951 Map of Unalaska

About this map

The Aleutian Islands chain, including the major landmasses of Unalaska Island and the eastern edge of Umnak Island, appears here in a mid-century reconnaissance survey. The complex coastline is defined by massive natural harbors such as Unalaska Bay, Beaver Inlet, and Makushin Bay, which provided critical shelter for maritime operations during the era. The terrain is dominated by the soaring Makushin Volcano and the Shaler Mountains, illustrating the volcanic origins of the archipelago.
