2021 Map of Sumdum A-4 SE

About this map

Franklin Peaks and Hamilton Peak rise above the coastal wilderness of Southeast Alaska in this topographic portrait of the Tongass National Forest. The landscape is defined by the sharp transition from the mountainous interior to the expansive waters of Frederick Sound along the southern coastline. This map details the intricate topography of the Missionary Range at the southern edge of the quadrangle, illustrating the steep coastal bluffs and glacial terrain characteristic of the Petersburg Borough. The lack of infrastructure or developed settlements highlights the isolation of this maritime environment, where the primary geographical markers are named summits and the deep tidal waters that serve as the region's main corridors.
