2020 Map of Unalaska C-1 NW
USGS Topo · Published 2020About this map
Unalaska Island is defined by its deep coastal indentations and mountainous interior, where the North Pacific and the Bering Sea meet. As part of the Fox Islands chain within the Aleutian Islands, the land here transitions from the heights of Lofty Mtn to dramatic coastal features such as Erskine Point and Brundage Head. The topography reveals a complex network of waterways, including English Bay, Deep Bay, and the narrow Unalga Pass, which separates landmasses in this maritime environment.
