1955 Map of Bradfield Canal A-1

About this map

Texas Glacier and a vast network of ice flows dominate this international border landscape within the Tongass National Forest during the mid-1950s. The map illustrates a high-altitude wilderness where glacial recession is evident in features like Disappearing Lake and the remnants of industrial efforts carved into the mountainsides. Along the Salmon River and Texas Creek, the presence of the Riverside Mine and an Aerial Tramway near Mineral Hill point to the difficult extraction of resources in this environment. Evidence of earlier travel and habitation along the boundary is found at the Boundary Roadhouse (Ruins) and Ninemile (Ruins), marking a period when these remote outposts served as critical stops for those navigating between Alaska and British Columbia. Surveyed during an era of aerial photogrammetry, the map captures the transition between the peak mining years and the preservation of the glacial wilderness.
