2017 Map of Petersburg B-4 NW

About this map

Kupreanof Island forms the northern coastline in this survey, where the dense wilderness of the Tongass National Forest meets the open waters of the Gulf of Alaska. The landscape is defined by rugged coastal features such as Douglas Bay and Moss Island, which provide natural sheltered pockets against the sea. To the south, the nautical importance of the region is evident in the marking of McArthur Reef, a critical maritime hazard situated well offshore. The map also delineates the administrative boundary between Petersburg Borough Prince of Wales-Hyder Census Area, illustrating the jurisdictional divisions within this remote stretch of Southeast Alaska. This documentation of the shoreline, including landmarks like Mitchell Point, serves as a precise record of the intersection between federal forest lands and the complex Alexander Archipelago waterway.
