USGS Topo · Published 2021About this map
Tongass National Forest dominates this coastal landscape, where the tides interact with the rugged Southeast Alaska shoreline. The topographic survey highlights the unique transition from the open waters of Hobart Bay to the inland-reaching waters of The Salt Chuck. This area is characterized by high-elevation relief and complex drainage patterns, most notably defined by the Chuck River as it winds through the forested interior. The mapping illustrates the vast wilderness of the Petersburg Borough, emphasizing the relationship between saltwater inlets and the heavily timbered drainages that define the region's geography.
