2021 Map of Petersburg D-5 SW

About this map

Tongass National Forest covers this coastal expanse of Southeast Alaska, where the high ridges of Greeberg Mountain and Crash Ridge overlook the intricate shoreline of the Alexander Archipelago. The landscape is defined by the proximity of high terrain to the tidal waters of Keku Strait and the sheltered Big John Bay. This 2021 survey illustrates a region largely characterized by its natural topography and drainage systems, including the headwaters of Hamilton Creek and the southern reaches of Big John Creek. Access to the interior is limited, primarily represented by the Big John Bay Trl, which connects the bay to the upland areas near Marble Knobs. The map highlights the intersection of the Prince of Wales-Hyder Census Area and the Petersburg Borough, providing a clear view of how these administrative lines traverse the wilderness near Irish Cr.
