2018 Map of Sumdum C-3 SW

About this map

The Coast Mountains dominate this high-altitude landscape within the Tongass National Forest, where massive ice fields and tidal waters meet. The sheet documents a critical glacial interface, featuring the northern reaches of North Dawes Glacier and Dawes Glacier, alongside the South Sawyer Glacier to the north. These frozen giants flow toward the saltwater of Endicott Arm, which marks the southern boundary of the map. The terrain is defined by extreme elevation changes and ice-carved topography, serving as a record of the region's wilderness state in the early 21st century. The map also delineates the administrative boundary between the Hoonah-Angoon Census Area and Petersburg Borough, cutting across the glaciated peaks of the southeastern Alaska panhandle.
