About this map

Sumner Strait and Clarence Strait converge in this mid-century maritime survey of Southeast Alaska, where the northern tip of Prince of Wales Island meets the jagged coastlines of Kupreanof Island and Zarembo Island. Navigational safety in these volatile waters is marked by vital landmarks such as Vichnefski Rock Light and The Eye Opener Light, while the inland topography reveals a system of freshwater drainage including Red Lake and Salmon Lake.

The presence of numerous small island groups like the Level Islands, Rookery Islands, and Bushy Islands indicates a complex coastal environment essential for local fishing and shipping routes. Coastal features such as Sandy Bight, Bay Pt, and the Rapids suggest the natural bottlenecks and shelter points known to mariners of the era. This chart reflects the 1950s landscape of the Tongass National Forest, documenting the intricate shoreline and hydrography as mapped by the U.S. Geological Survey and USC&GS.
