1948 Map of Sumdum A-6

About this map

Frederick Sound dominates the northern reaches of this coastal landscape, where the waters of the Keku Strait meet the rugged northern shoreline of Kupreanof Island. Based on aerial photography from the late 1940s, the map reveals a wilderness largely untouched by formal roads or settlements, preserved within the Tongass National Forest. Inland, the terrain rises sharply toward Turn Mountain, while the coastline is defined by hazardous maritime features like Pinta Rocks, Schooner Rock, and the isolated Turnabout I. The drainage of Gunnuk Creek offers a rare named interior landmark, carving through the dense topography of this Alexander Archipelago environment. This survey captures a moment of pure topographical documentation before significant modern development, focusing on the interface between the maritime passages and the high, forested ridges of the island.
