2017 Map of Three Fingered Jack

About this map

Three Fingered Jack dominates the skyline of the Cascade Range, marking a dramatic intersection where the borders of Linn, Jefferson, and Deschutes counties meet. This 2017 survey details a landscape defined by volcanic landmarks and an extensive network of high-elevation trails, including the Pacific Crest National Scenic Trail and the historic Old Summit route. The area around Santiam Pass serves as a central corridor for modern and traditional travel, surrounded by distinctive geologic formations like Hayrick Butte and Claypool Butte. A dense concentration of alpine water bodies, from the larger Suttle Lake and Big Lake to smaller basins like Square Lake and Booth Lake, illustrates the glaciated character of the terrain. The map also highlights significant recreational and ecological zones within the Willamette National Forest and Deschutes National Forest, such as the verdant Canyon Creek Meadows.
