2021 Map of Unalaska B-3 NE
USGS Topo · Published 2021About this map
Portage Bay and Cannery Bay deeply indent the coast of Unalaska Island on this 2021 topographic sheet, illustrating the maritime character of the Aleutian landscape. The prominence of Cannery Point suggests the historical industrial use of these protected waters, where the geography of the Pacific Ocean creates sheltered inlets like Samgan Udaa and Udamak Cove. This survey details a terrain defined by steep coastal elevations and maritime landmarks, including Peter Island and Gull Island, which serve as critical navigation points along the shoreline. The land is organized by the Public Land Survey System, shown through township markers such as t75s r120w, marking out the uninhabited reaches of the Aleutians West Census Area.
