2021 Map of Unalaska B-3 SW

USGS Topo · Published 2021

About this map

Unalaska Island dominates this 2021 topographic survey, showcasing the severe, unpopulated terrain of the Fox Islands chain. Located within the broader Aleutian Islands, the land is defined by steep elevation changes and intricate coastal inlets. The northwestern corner reveals the protected waters of Skan Bay, while the southwestern shoreline meets the open Pacific Ocean. This map highlights the raw geological character of the region, where high peaks drop sharply toward the sea, largely untouched by permanent settlements or infrastructure. The inclusion of the Public Land Survey System boundaries, such as t76s r121w and t77s r122w, provides a modern administrative grid over this ancient volcanic landscape, useful for researchers tracking land management in the Aleutians West Census Area.
