2017 Map of Sumdum C-5 SW

About this map

Tongass National Forest dominates this coastal Alaska landscape, where steep maritime slopes meet the waters of Stephens Passage. The topography is defined by sharp elevation changes rising directly from the shoreline, particularly around the prominent headland of Point Windham. To the south, Sunset Island sits just off the coast, marking the entrance to more protected waters near Windham Bay. This 2017 survey by the U.S. Geological Survey details a wilderness area where the absence of roads or permanent settlements reflects the remote nature of the Unorganized Borough. Mapping here focuses on the complex intersection of deep-water channels and high-relief coastal terrain typical of the Alexander Archipelago.
