2017 Map of Sumdum A-4 SW

About this map

Frederick Sound dominates this coastal landscape within the Tongass National Forest, illustrating the intricate shoreline of the Alexander Archipelago. This survey focuses on the maritime intersections of the Petersburg Borough boundary as it traverses open water and rugged islands. The northern portion of the map is defined by the entrance to Farragut Bay, guarded by Read Island and Grand Point. To the south, the northern coastline of Kupreanof Island reveals a series of prominent navigational markers, including Boulder Point and the passage through Cape Strait. The absence of developed roads or settlements highlights the isolation of these forested reaches, where transport relied entirely on the waterways connecting Portage Bay to the larger sound.
