2021 Map of Sumdum C-4 NE

About this map

Tongass National Forest dominates this coastal Alaska landscape, where massive ice fields and deep glacial fjords define the topography. The map centers on the high-altitude interface between the North Sawyer Glacier and the South Sawyer Glacier, showcasing the dramatic elevation changes characteristic of the region. To the west, the waters of Fords Terror cut into the mainland, illustrating the steep-walled inlets that provide access to this wilderness. This 2021 edition reflects the modern boundaries of the Hoonah-Angoon Census Area and the Petersburg Borough, which meet along the high mountain ridges. The lack of roads or established settlements emphasizes the character of the area as a protected maritime forest and glacial preserve, where geographic features are the primary landmarks for navigation.
