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.
