1951 Map of Umnak

Thermal activity is evident throughout the island, particularly near Geyser Bight and Hot Springs Cove, while coastal landmarks like Steeple Point and the Bolling Pinnacles illustrate the dramatic shoreline topography. A lone Cemetery near Inanudak Bay and various named points like Cape Tanak and Cape Chagak provide essential data for those studying the remote settlement and maritime history of the Fox Islands. To the north, the isolated forms of Bogoslof Island and Fire Island rise from the Bering Sea.
