2021 Map of Sumdum C-3 NW

USGS Topo · Published 2021

About this map

Tongass National Forest dominates this high-altitude landscape in Southeast Alaska, where deep glacial-carved terrain meets complex administrative boundaries. This survey documents a critical junction point where the Hoonah-Angoon Census Area and Petersburg Borough meet, tracing a line across the wilderness. The lack of named roads or settlements highlights the isolation of this part of the Alexander Archipelago, where the natural contours of the land dictate the limits of human activity. Grid lines from the Public Land Survey System, including t48s r77e and t48s r78e, provide a framework for navigating this heavily glaciated and largely trackless region, offering researchers a detailed look at the geographical division of these Alaskan administrative districts at the start of the 2020s.
