About this map

Sweet Home and Springfield anchor this 1983 topographic study of the western Cascades, where the timber and water resources of Linn County and Lane County are on full display. The map documents a landscape defined by significant 20th-century water management projects, including the impoundments of Foster Lake, Green Peter Lake, and Cougar Reservoir. These reservoirs sit amidst the expansive Willamette National Forest, contrasting with the more settled river valleys to the west.

Transportation networks are heavily influenced by the terrain, with the Southern Pacific railroad and Oregon 126 following the winding path of the McKenzie River. Smaller settlements like Crawfordsville, Mabel, and Wendling illustrate the historical distribution of valley communities. To the east, the map reaches the high-elevation protected lands of the Three Sisters Wilderness, showing the transition from industrial forest and agricultural valleys to the preserved alpine environment.
