2017 Map of Petersburg D-4 NW

About this map

Kupreanof Island dominates this portion of the Tongass National Forest, where the waters of the Gulf of Alaska meet a complex network of coastal inlets and steep peaks. The geography is defined by the transition from Portage Bay into the interior wilds of the Missionary Range, with high points such as Chipp Peak and Putnam Peak towering over the drainages of Goose Creek. For those navigating the shoreline, landmarks like Flat Point, Hook Point, and Harrington Rock provide essential orientation in the marine environment of the Petersburg Borough. The interior remains largely untouched, characterized by the Portage Mountain Loop Trail winding through the forest toward Petersburg Lake, illustrating the isolation and specialized land use common in this part of Southeast Alaska.
