1959 Map of Three Fingered Jack

About this map

Three Fingered Jack and Mt Washington dominate this mid-century survey of the High Cascades, where the convergence of the Willamette National Forest and Deschutes National Forest reveals a landscape defined by volcanic activity. The presence of the Old Santiam Railroad Grade and the Cache Creek Toll Station points to a history of trans-mountain passage through the lava fields. This era shows the development of the Santiam Highway corridor, connecting Santiam Junction to recreation hubs like Suttle Lake and Blue Lake. Between the cinder pits and gravel pits, the network of paths including the Oregon Skyline Trail and Minto Pass Trail provided access to high-elevation water bodies like Duffy Lake and Big Lake, which were essential landmarks for forest management and back-country travel before more modern infrastructure arrived.
