2017 Map of Petersburg C-1 NW

About this map

The Stikine River delta dominates this landscape within the Tongass National Forest, showing a complex network of braided channels and silty deposits. A striking geological transition occurs where the high peaks of Mt Basargin and the Popof Glacier give way to the low-lying glacial outwash plains. An unusual feature known as The Desert sits between Andrew Slough and the main river channel, representing a massive accumulation of river sediment. This survey documents the shifting aquatic environment surrounding Andrew Island and Limb Island, where numerous waterways like Andrew Cr and N Arm Cr carve through the temperate rainforest. The map captures the boundary between the Petersburg Borough and Wrangell, marking a remote wilderness where landforms like Kakwan Point and Hooligan Point overlook the active river system.
