2021 Map of Sumdum C-3 SE

USGS Topo · Published 2021

About this map

Dawes Glacier and South Sawyer Glacier dominate this remote glaciated landscape within the Tongass National Forest. Located along the high ridges of the Coast Mountains, the area marks a significant administrative boundary where the Hoonah-Angoon Census Area meets the Petersburg Borough. The 2021 survey illustrates the extensive ice fields and steep topographic relief characteristic of this part of Southeast Alaska, showing how the massive glaciers carve through the high-elevation terrain. This map provides a precise record of the ice extent and drainage patterns in a region where the natural environment is defined by these slow-moving frozen rivers and the sharp peaks that contain them.
