1955 Map of Bradfield canal B-3

USGS Topo · Published 1959

About this map

Tongass National Forest dominates this mid-century topographic study of the remote Alaskan wilderness bordering British Columbia. The landscape is defined by the significant glacial and fluvial systems of the Blue River valley, where the water flows through narrow passages like First Canyon and past the distinctive Lava formations. High-altitude features including Mt Stoeckl, Dickins Pk, and Mosheim Dome provide steep relief, with Crevasses marked on the ice-laden slopes. A singular Cable Car installation near the river indicates the difficulty of traversing this terrain before modern infrastructure. This 1950s survey reflects the ongoing work of the International Boundary Commission along the Canada United States border, capturing the drainage patterns of Blue Lake and Hell Roaring Creek in a period of active aerial photogrammetric mapping.
