2024 Map of Sumdum A-4 SE

About this map

Tongass National Forest dominates the steep, mountainous landscape of this coastal Alaskan region, where the high ridges of Franklin Peaks and Hamilton Peak overlook the deep waters of Frederick Sound. The interaction between the maritime environment and the high-elevation terrain is evident in the drainage patterns leading toward Dry Bay, a protected cove on the northeastern edge of the sound. This 2024 topographic study reveals a largely roadless wilderness defined by extreme relief and the complex shoreline of Southeast Alaska's internal waterways. The map preserves the specific survey boundaries of t55s r77e and t55s r78e, documenting the spatial organization of this protected federal land within the Petersburg Borough.
