2021 Map of Sumdum C-6 SW

About this map

Seymour Canal dominates the central portion of this coastal topographic survey, dividing the steep terrain into distinct eastern and western ridges. This landscape is entirely contained within the Tongass National Forest, illustrating the remote and protected character of the Alexander Archipelago. On the western landmass, Yeek-Sha Mtn rises sharply from the shoreline, its steep contours reflecting the dramatic vertical relief of the Alaska Panhandle. The map reveals a wild, unpopulated environment defined by glacial geology and dense forest, where the only human-imposed structures are the cadastral boundary lines of townships t49s r71e and t50s r71e. The detailed hydrography shows numerous small drainage patterns feeding into the canal, marking a wilderness state largely untouched by modern development.
