2021 Map of Petersburg C-6 NE

About this map

Keku Strait defines the central character of this Southeast Alaska coastal landscape, separating the rugged forested interior from a network of small islands. Within the vast boundaries of the Tongass National Forest, the terrain rises from the tidal flats of Mud Cr and Irish Cr toward interior heights such as The Summit. The map details a complex maritime environment where large landmasses like Kupreanof Island are fringed by smaller features including High Island, Summit Island, and the uniquely named Brown Bear Head Island. This 2021 update illustrates the preservation of a roadless wilderness, where the geography of the Alexander Archipelago remains shaped by water and high-relief topography rather than human infrastructure or settlement.
