1959 Map of Three Fingered Jack

About this map

Santiam Highway and the McKenzie Highway converge in this high-altitude landscape where the Cascade Range defines the boundary between the Willamette National Forest and Deschutes National Forest. The 1959 survey records a transition from the historic Old Santiam Wagon Road and an Old Railroad Grade to modern automotive access at Santiam Junction. Distinctive geological features dominate the terrain, from the sharp peaks of Three Fingered Jack and Mt Washington to the cinder-strewn basins around Belknap Crater and Nash Crater. A network of high lakes like Big Lake, Duffy Lake, and Square Lake serve as focal points for early recreational developments such as Camp Tamarack and numerous forest camps, while legacy industrial markers like the Cinder Pits near Potato Hill reflect the local extraction of volcanic materials.
