2021 Map of Unalaska B-3 NW

About this map

Cathedral Point and the dramatic coastal formations of Cathedral Rocks define the northern shoreline of this maritime landscape in the Aleutians West Census Area. The region is characterized by deep glacial indentations including Makushin Bay and Humpback Bay, where the land meets the Pacific Ocean. This survey details a remote volcanic environment where steep interior contours descend toward prominent coastal landmarks like Tarasof Point and Iksiak Point. Small islands such as Peter Island sit offshore near Anderson Bay, illustrating the fragmented coastline of the archipelago. Further south, the map tracks the sheltered waters of Naginak Cove and Skan Bay, providing a precise look at the uninhabited natural harborages and terrain of Unalaska Island.
