2021 Map of Adak D-1 SW

About this map

Bering Sea and the northern reaches of Sitkin Sound dominate this maritime survey of the Aleutian landscape. The map focuses on the western coastline of a remote island landmass, defined by prominent geographical landmarks such as Saddle Point in the north and Cape Kiugilak at the southern edge. The interior topography is marked by named summits and ridges including Kyuugaadax and Uugangax, rising sharply from the shoreline. This modern survey, produced by the U.S. Geological Survey, illustrates the interplay between the deep waters of the North Pacific and the high-relief terrain of the Aleutian chain. The lack of infrastructure or settlements on this sheet highlights the isolated nature of the terrain, where coastal features like Cape Akuyan serve as the primary points of reference for navigation and geographical study.
