2021 Map of Attu A-2 SW
USGS Topo · Published 2021About this map
Bering Sea waters dominate the northern extent of this maritime survey in the Aleutian Islands. The region is largely defined by open water and its offshore location within the Public Land Survey System, specifically falling within township t90s r264w and t90s r263w. As a modern data set, this 2021 study reflects the precise geodetic positioning of the remote waters at the westernmost edge of Alaska. Because the landscape here is predominantly oceanic, the map serves as a primary record of maritime boundaries and nautical coordinates in a sparsely named section of the Pacific frontier.
