2021 Map of Sumdum C-2 SW

USGS Topo · Published 2021

About this map

Boundary Peak 73 stands as a primary survey marker on the international divide where the United States and Canada border cuts through the southeastern Alaska wilderness. This high-altitude landscape is characterized by its dramatic glacial activity and the rugged terrain of the Tongass National Forest. The map delineates the administrative intersection of the Hoonah-Angoon Census Area and the Petersburg Borough, showing how these modern boundaries follow the natural crests of the mountains. To the north, the massive ice flow of Sawyer Glacier dominates the drainage, illustrating the persistent ice fields that define the interior of the Sumdum region. The lack of roads or established settlements emphasizes the wilderness character of the T49S and T50S townships along this high-latitude frontier.
