2021 Map of Unalaska A-6 SE

USGS Topo · Published 2021

About this map

Lone Peak dominates the interior of this coastal terrain on Unalaska Island, a landscape shaped by extreme maritime geography. This 2021 survey details the southwestern reaches of the island where the land meets the Pacific Ocean at sharp coastal projections like Konets Head and Tiderip Point. To the north, the waters of Umnak Pass and Boulder Bay are marked by significant submarine features such as the West Bogoslof Canyon and the isolated Ship Rock islet. Large portions of this territory fall within the Alaska Maritime National Wildlife Refuge, indicating a protected wilderness character defined by its isolation and lack of established road networks. The intricate contour lines reveal the steep elevation gains characteristic of the Aleutian Chain's volcanic topography.
