1948 Map of Sumdum B-6

USGS Topo · Published 1957

About this map

Admiralty Island dominates the western half of this maritime survey, illustrating the complex coastline within the Tongass National Forest shortly after the war. The map documents a network of islands and deep-water inlets, including Gambier Bay and Pybus Bay, which served as critical sheltered waters for navigation. The presence of the Gambier Bay Entrance Light underscores the importance of maritime safety in these channels, where Stephens Passage and Frederick Sound converge.
