2017 Map of Petersburg C-5 SW

About this map

Kupreanof Island dominates this 2017 survey, showcasing a landscape defined by the intricate hydrology of the Tongass National Forest. The map documents the drainage patterns of the region, where Tunehean Creek and its many tributaries, including Tunehean Cr, flow through heavily contoured terrain toward the coast. Farther south, Lovelace Cr carves through the central portion of the quadrangle, while the southeast corner is anchored by the waters of Kushneahin Lake. This topographical study reveals the undisturbed nature of the Petersburg C-5 SW quadrangle, illustrating the complex elevation changes and dense wetland networks that characterize the Alaskan wilderness within the borough. The absence of roads or permanent settlements highlight the area's role as a pristine natural corridor.
