2021 Map of Unalaska A-4 NW

About this map

Unalaska Island, part of the Fox Islands in the larger Aleutian Islands chain, presents a landscape defined by dramatic maritime interfaces and steep coastal topography. The coastline is deeply indented by substantial water bodies such as Kismaliuk Bay and Alimuda Bay on the western shore, while Kashega Bay and the smaller Buck Bight open toward the Bering Sea to the northeast. This 2021 topographic survey provides a precise look at the points and pinnacles that guide navigation in these northern waters, including the sharp Kashega Pinnacles and the southern reach of Buttress Point. The interior is largely dominated by high-relief terrain, with the map reaching south to the Pacific Ocean near Tower Point, illustrating the narrow breadth of the island at this specific northern latitude.
