2021 Map of Unalaska B-4 NE

About this map

Makushin Bay and Skan Bay dominate this coastal survey of the Unalaska island chain, where the eastern shoreline meets the vast Bering Sea. The terrain is defined by dramatic coastal features like the high-relief Cape Starichkof and the prominent Kof Point. The presence of the Bogoslof Basin suggests complex seafloor topography just off the coast, while the interior landscape is marked by steep elevation rises moving inland from Skan Point. This map provides a clear record of the uninhabited maritime environment, focusing entirely on the natural geography and nautical landmarks that define this portion of the Aleutian Islands.
