About this map

Illahee Rock and the high ridges of the Cascades dominate this mid-century survey of the Umpqua River headwaters. The map documents a wilderness transitioning into a managed timber and recreation resource, characterized by a network of lookouts and shelters such as Chilcoot Mtn and the Fairy Shelter. Along the river banks, established sites like Apple Creek Forest Camp and the Illahee Guard Sta provide evidence of early Forest Service administration in the area.

Water-driven features are prominent, from the hydroelectric infrastructure of the Power House to the natural cascades at Steamboat Falls and Little Falls. Industrial history is whispered through the presence of Loughs Mine near the river, while the landscape is dotted with named camps such as Johnson Camp and Wild Rose Camp. The intricate system of named ridges, including Washboard Ridge and Bradley Ridge, underscores the complex topography that historically challenged travel and early surveying efforts.
