2020 Map of Unalaska B-2 SE

USGS Topo · Published 2020

About this map

The Pacific Ocean dominates this maritime expanse within the Aleutians West Census Area, reflecting the isolation of Alaska's southwestern volcanic archipelago. This 2020 survey focuses almost entirely on the open sea, providing an essential record of the coastal approaches and hydrographic environment surrounding the Unalaska region. While devoid of land-based settlements or structures, the sheet is strictly organized by the Public Land Survey System, with township and range lines such as T76s R118w and T77s R119w defining the maritime grid. This cartographic layout serves as a primary reference for maritime navigation and jurisdictional boundaries in a region where the land gives way to the deep waters of the North Pacific.
