2018 Map of Sumdum C-2 SW

About this map

The Canada-United States border defines the eastern reach of this high-altitude landscape, where the Tongass National Forest meets the international boundary. This area is dominated by massive ice fields and glacial movements, most notably the sprawling Dawes Glacier which carves through the southern portion of the map. The terrain is characterized by sharp elevation changes, anchored by Boundary Peak 75 along the frontier line. Water drainage is largely dictated by the glacial melt, including the headwaters of South Fork Creek. This map captures a remote section of the Hoonah-Angoon Census Area and Petersburg Borough, illustrating the stark interface between protected Alaskan wilderness and the British Columbia interior before modern climate shifts further altered the glacial extent.
