2017 Map of Sumdum A-4 SE

About this map

Tongass National Forest dominates the terrestrial landscape of this coastal survey, where steep terrain rises sharply from the waters of Frederick Sound. The shoreline of Petersburg Borough is marked by a dramatic transition from maritime environments to high elevations, punctuated by prominent summits. In the northern reaches, Hamilton Peak stands as a significant landmark, while Hancock Peak anchors the terrain further south along the coast. This mapping captures the intricate relationship between the coastal shelf and the massive National Forest system in Southeast Alaska. The map provides a clear look at the Public Land Survey System grid, including township markers such as t55s r77e and t55s r78e, which serve as primary reference points for researchers and land managers navigating this wilderness region.
