About this map

Atka Island sits at the far western edge of this coastal survey, where the terrestrial terrain of the Aleutian Islands meets the open expanse of the Bering Sea. The map focuses primarily on the maritime environment and the delicate shoreline near Cape Shaw, a prominent land feature in an area defined more by its nautical boundaries than by inland settlement. Detailed surveying from agencies like the U.S. Geological Survey and the Bureau of Land Management establishes the Public Land Survey System grid, including t91s r174w and t91s r175w. This document captures the remote character of the Aleutians West Census Area, providing an essential record of the island's coastline and the surrounding waters for maritime and geographic study.
