2021 Map of Sumdum C-6 NE

About this map

Stephens Passage dominates the central aquatic landscape of this 2021 survey, serving as a primary maritime corridor through the Alexander Archipelago. The map captures a section of the Tongass National Forest where the rugged coastline of the mainland meets the coastal waters of Southeast Alaska. This maritime boundary is marked by distinct navigational hazards and landmarks including Thistle Ledge and the prominent heights of Point Lookout. The interface of land and sea is further detailed at Dry Bay and Point League, providing a high-resolution look at the shoreline as it existed in the early 21st century. The map also delineates the administrative border between the Hoonah-Angoon Census Area and Petersburg Borough, illustrating how modern political boundaries bisect this complex glacial landscape.
