About this map

Kupreanof Island dominates this portion of the Alexander Archipelago, showing the wild coastal character of the Lindenberg Peninsula within the Tongass National Forest. The southwestern coastline is defined by the tidal reaches of Duncan Canal, where the terrain transitions from the water's edge into a network of drainage-based forest roads. The presence of routes like Mitchell-Tonka and Alpine indicates a landscape shaped by forest management and resource access. Small topographic details such as Siwash and various creek-aligned tracks including Brown Creek, Schia-De, and Gelch-De reveal the intricate layout of the interior hillsides above the canal. This map documents the intersection of maritime geography and federal forest lands in a region where travel is primarily dictated by the shoreline and established timber routes.
