About this map

The Shaler Mountains dominate the central topography of this section of Unalaska Island, rising between a complex network of glacial fjords and inlets. The coastline is defined by deep indentations such as Makushin Bay in the northwest and the extensive Usof Bay to the southeast, illustrating the maritime character of the Aleutian chain. Inland, the terrain is characterized by steep summits and dramatic coastal features like Cathedral Rocks near Humpback Bay.

The presence of Cannery Bay and Cannery Point points toward the commercial fishing and processing heritage of the region. This 1989 provisional survey captures the island's landscape through photogrammetry, recording landmarks like Peter Island and Gull Island within the protected waters of Anderson Bay. The map lacks established roads or trails, highlighting the reliance on water transport between points like Naginak Cove and Johnson Cove.
