About this map

Umnak Island, situated within the Fox Islands chain of the Aleutian Islands, marks the northwestern extent of this maritime landscape. The map focuses on the southern reaches of the island where the landmass tapers into the vast expanse of the Pacific Ocean. Contours here trace the high coastal elevations that drop sharply toward the shoreline, a characteristic feature of the volcanic topography found throughout this region of Alaska.

The structural framework of the Public Land Survey System is visible through township designations like t83s r135w and t84s r135w. While the majority of the area is dominated by open water, the terrestrial portion represents a remote segment of the Aleutians West Census Area, preserving the coastline as it existed in the early 21st century. This survey provides a precise look at the intersection of the rugged island fringe and the surrounding sea.
