2021 Map of Unalaska B-3 SE

USGS Topo · Published 2021

About this map

The Shaler Mountains dominate the interior of this coastal Aleutian landscape, rising sharply from the waters of the Pacific Ocean. This high-altitude terrain is marked by steep elevation changes that drop into the protected waters of Usof Bay and Blueberry Bay to the southeast. The survey highlights a remote coastal interface where glacial or tectonic activity has carved deep indentations like Johnson Cove, creating a complex shoreline typical of Unalaska Island. The absence of roads or permanent settlements in this quadrangle reflects the extreme isolation of the Aleutian range during the early twenty-first century, with the land defined primarily by its vertical relief and maritime boundaries.
