2017 Map of Sumdum C-4 SE

About this map

The Coast Mountains dominate this 2017 survey, where dramatic ice and saltwater meet in the heart of the Tongass National Forest. The landscape is defined by its deep maritime fjords and the descending ice of the North Dawes Glacier, which occupies the upper northeastern corner of the quadrangle. This map documents a wilderness landscape largely devoid of human infrastructure, focusing instead on the physical relationship between the mountain peaks and the tidal waters that reach into the interior. The topographic detail traces the steep elevation changes from sea level up into the high alpine zones of the Alaska Panhandle, providing a precise record of the shoreline and glacial extent as they appeared in the early 21st century.
