2017 Map of Sumdum D-4 SE
USGS Topo · Published 2017About this map
The Sawyer Glacier and South Sawyer Glacier dominate the high-altitude topography of the Coast Mountains within the Tongass National Forest. This 2017 survey documents the glacial extent and the sheer verticality of the terrain, where ice-carved valleys and steep ridges define the landscape of the Hoonah-Angoon Census Area. The map highlights the intersection of coastal glacial systems with the protected boundaries of the national forest, illustrating the intricate drainage patterns and geological formations characteristic of Southeast Alaska. Without roads or settlements, the sheet serves as a primary record of the glacial margins and mountainous backcountry in the t46s r76e and t47s r77e townships.
