2017 Map of Sumdum C-6 NE

About this map

Stephens Passage dominates this 2017 survey, defining the marine landscape of the Unorganized Borough between the Hoonah-Angoon Census Area and Petersburg Borough boundary. The map illustrates a coastline characterized by maritime landmarks such as Thistle Ledge and the sheltered waters of Dry Bay. On the eastern shore, the terrain rises into the protected reaches of the Tongass National Forest, where prominent coastal features like Point Lookout and Point League serve as vital navigation points. The absence of roads or established settlements reflects the wilderness character of this Southeast Alaska corridor, where the land-sea interface remains governed by the tides and the expansive national forest system rather than industrial or urban development.
