About this map

Great Sitkin Island dominates the northern reaches of this maritime landscape in the Bering Sea, characterized by the complex coastlines and volcanic terrain of the Aleutians West region. Significant coastal markers like Zaliva Point and Rip Point define the southern edge of the island, while to the south, a chain of smaller landmasses including Tanaklak Island, Kanu Island, and Asuksak Island are separated by deep water channels such as Great Sitkin Pass and Asuksak Pass.

The southern portion of the survey is anchored by the northern face of Umak Island, where Cape Chakik extends into the sea near the indentation of Umak Bight. The distribution of these islands suggests the intricate navigational challenges of the area, with numerous islets like Box Island and Aziak Island providing additional landmarks for those studying the geological and maritime history of the Aleutian chain.
