2020 Map of Port Moller A-4 NE

USGS Topo · Published 2020

About this map

The Pacific Ocean dominates this maritime survey, illustrating a remote stretch of the Aleutian chain within the Kennoys Islands group. The map provides a precise layout of the Public Land Survey System (PLSS) across these waters, defining the boundaries for t57s r78w, t57s r77w, and t58s r78w. This specific focus on nautical boundaries and small island clusters highlights the administrative organization of Alaska's maritime reaches, where landmasses are sparse but territory is strictly delineated by township and range coordinates. It is an essential reference for understanding how geographic grids are applied to the open sea and isolated island chains in the Aleutians East Borough.
