2021 Map of Unalaska B-4 SE

USGS Topo · Published 2021

About this map

Unalaska Island is mapped here along its southwestern shoreline, where the land meets the cold waters of the Bering Sea. The terrain is characterized by steep coastal elevations and deep inlets, most notably the sheltered waters of Pumicestone Bay. This 2021 topographic survey reveals a landscape of high ridges and narrow valleys, with prominent coastal features like Spray Cape and Kashega Point marking the transition from the island's interior to the open sea. Part of the Fox Islands chain within the Aleutian Islands, the area's geography is defined by its dramatic relief, reaching thousands of feet in elevation just miles from the coast. The lack of roads or established settlements emphasizes the wilderness character of this maritime region.
