USGS Topo · Published 2021About this map
Tongass National Forest dominates this coastal landscape in the Petersburg Borough, where the maritime environment meets the forested interior. The prominent Point Agassiz Peninsula extends into the waters near the intersection of Thomas Bay and Bock Bight, creating a complex shoreline defined by landmarks such as Wood Point and Prolewy Rocks. This area is characterized by its lack of dense development, favoring remote access points like the Colp Lake Trl and the Point Agassiz Connection.
