The Bering Sea dominates this maritime survey of a remote portion of the Aleutian Islands. The map focuses on the watery corridors of Segula Pass and Sea Lion Pass, essential passages through the archipelago. This 2021 update relies on SPOT satellite imagery and data from the Alaska Department of Transportation to delineate the stark coastline and navigation hazards of the region. Notable among these is the solitary Sea-Lion-Rock, a critical landmark for maritime navigation in these turbulent waters. The inclusion of Public Land Survey System data, such as t96s r233w, provides a administrative layer to a landscape otherwise defined by tide and swell, offering a precise look at the contemporary geographical state of the Rat Islands chain.
