2021 Map of Petersburg D-4 SW

About this map

Tongass National Forest dominates this coastal landscape, where the tides of the North Arm Duncan Canal meet the steep topography of Portage Mtn. The map highlights a significant transition between the marine environment of Duncan Canal and the interior freshwater of Petersburg Lake. Traces of local passage and communication are evident in the south, where the White Alice and White Alice Trl indicate routes near Mitchell Tonka. The presence of these named paths, alongside waterways like Olman Slough and Duncan Cr, illustrates the area's reliance on both riverine and overland travel. From the high elevations of Duncan Peaks to the shoreline at Goose Point and Indian Point, this map documents the intricate coastline and wilderness corridors of Southeast Alaska in the early twenty-first century.
