About this map

Tongass National Forest dominates this section of the Alaskan wilderness, where the high-altitude terrain is defined by the intersection of several major ranges. The Lincoln Mountains occupy the central portion of the sheet, while the Coast Mountains rise to the east and the Seward Mountains stretch across the southwest. This landscape is a primary watershed for the region, characterized by deep glacial valleys that channel the Davis River and the N Fork Soule River. The boundary between Ketchikan Gateway Borough and Prince of Wales-Hyder Census Area cuts diagonally through these peaks, marking a significant administrative division in a largely roadless environment. Smaller drainage systems like Thumb Cr feed into the larger river basins, illustrating the complex hydrology of the Alexander Archipelago's mainland interior.
