2021 Map of Petersburg B-3 NW

About this map

Saint John Harbor serves as the primary maritime entry point for this portion of Zarembo Island, sheltered by Northerly Island and Southerly Island. The map documents a complex network of forest roads and trails within the Tongass National Forest, illustrating how industry and recreation penetrate the coastal wilderness. Named routes such as Skyline, Muskeg Run, and Eyeopener crisscross the interior, providing access to landmarks like St John Knob and the low-lying Zarembo Flats. The boundary line for the Petersburg Borough Wrangell City and Borough cuts across the northern waters, while the interior is dominated by the hydrology of Zarembo Lake. This 2021 update captures the modern footprint of timber and management roads in a region where the shoreline, from Low Point to the coastal inlets, remains the defining geographic feature.
