2021 Map of Sumdum B-2 NW
USGS Topo · Published 2021About this map
Dawes Glacier dominates the upper-central portion of this high-latitude survey, marking a landscape where ice and elevation define the geography. Situated within the Tongass National Forest, the terrain is dominated by steep contours and glacial fields that straddle the international border. The northeastern corner is anchored by Boundary Peak 74, a significant marker along the frontier between the United States and Canada. This specific sheet focuses on a high-altitude glacial environment where the ice flow and topographic peaks are the primary landmarks, showing no human settlements or road infrastructure, only the raw physical boundary and the protected forest lands that encompass the region.
