2021 Map of Unalaska A-5 SE

About this map

Cape Alak defines the southwestern coastline of this remote Aleutian terrain, where the steep interior slopes drop precipitously toward the Pacific Ocean. This 2021 study by the U.S. Geological Survey documents a rugged, unpopulated landscape characterized by dense contour intervals and deep coastal indentations. The survey shows the complex topography of the Unalaska region, with elevations rising sharply from the shoreline into unnamed interior peaks. The mapping includes Public Land Survey System identifiers such as t78s r125w and t79s r125w, providing a precise grid over this uninhabited maritime environment. It is a portrait of raw Aleutian geography, recording the natural state of the coastline and the surrounding waters without the presence of modern roads or settlements.
