2021 Map of Unalaska C-4 SE

USGS Topo · Published 2021

About this map

Unalaska Island is defined here by its extreme maritime terrain and deeply indented coastline along the Bering Sea. This portion of the Fox Islands archipelago exhibits the dramatic elevation changes characteristic of the Aleutian Islands, where the land rises sharply from the water at Cape Kovrizhka toward the inland heights of Magusim Aligii. The map documents two significant maritime inlets, Volcano Bay and Makushin Bay, which are separated by a mountainous peninsula terminating at Makushin Point. This topographic survey provides a precise record of the shoreline and high-latitude relief in a region where few permanent settlements exist, focusing instead on the landforms that dictate navigation and survival in the North Pacific.
