2021 Map of Petersburg D-1 SW
USGS Topo · Published 2021About this map
Tongass National Forest dominates this Alaskan landscape, where steep maritime topography meets the glacial waters of Shakes Lake. Located at the boundary of Petersburg Borough and Wrangell City and Borough, the terrain is defined by extreme elevation changes and vast wilderness areas characteristic of the Southeast Alaska panhandle. The map illustrates a complex network of glacial valleys and ridges, with the borough boundary following high mountain crests. This 2021 survey serves as a modern record of glacial extent and shoreline stability in a region where geography dictates the limits of human activity and political jurisdiction.
