About this map

Three Fingered Jack rises as the central landmark of this high-country landscape, where the boundaries of the Mt Jefferson Wilderness, Willamette National Forest, and Deschutes National Forest converge. The terrain is defined by its glacial and volcanic features, including the prominent Hayrick Butte and Hogg Rock. The map illustrates a crossroads of historical and modern transit through Santiam Pass, where the Pacific Crest National Scenic Trail intersects with the trace of an Old Wagon Road.

Recreational development is evident at the Hoodoo Ski Bowl and numerous alpine water bodies like Square Lake and Blue Lake. A Historical Mon near the pass marks the intersection of Linn, Jefferson, and Deschutes counties, grounding the map in the administrative history of the Cascades. The survey also captures the drainage patterns of Canyon Creek and First Creek, which flow through a landscape of dense timber and lava fields.
