1955 Map of Bradfield canal A-3

About this map

Glacial valleys and high-altitude drainage systems dominate this mid-century survey of the Tongass National Forest. The braided channels of the Unuk River and the Leduc River cut through the terrain, fed by unnamed alpine lakes and high peaks. Evidence of human presence is minimal in this wilderness, though a solitary Cabin is marked in the northern reaches near Sawmill Slough. The mapping relies on aerial photography from 1948, capturing the landscape before the widespread use of modern satellite tracking. Survey markers like Vabm 4138 Lake and Vabm 5681 Jims provide fixed points across the ice-scoured heights. The map also traces the winding course of the Klehini River and Lake Creek, illustrating the complex hydrology of the Alaskan panhandle.
