2021 Map of Sumdum D-4 SW

USGS Topo · Published 2021

About this map

Tongass National Forest dominates this Alaskan wilderness, where the high elevations of the Coast Mountains define the physical landscape. This 2021 survey illustrates the remote borderlands where the Hoonah-Angoon Census Area meets the Petersburg Borough. The map captures a largely untouched environment, characterized by steep elevation changes and extensive glacial or ice-covered terrain typical of the region's high-latitude maritime climate. The lack of infrastructure or named settlements highlights the area's role as a vast protected forest and mountain range, serving as a baseline for modern topographic study and resource management in Southeast Alaska.
