Sanak Island and the surrounding Sanak Islands anchor this 1989 maritime study of the eastern Aleutian archipelago. The map reveals a complex coastal landscape of protected inlets like Peterson Bay and Northeast Harbor, which historically served as critical shelter for fishing and sealing vessels. Much of the eastern portion of the sheet is designated as the Aleutian Islands Wilderness, encompassing Caton Island and smaller landmasses such as Elma Island and Gunboat Island.
