Deschutes National Forest land defines this central Oregon landscape, where volcanic features and an extensive network of recreation trails dominate the terrain. Significant elevations include Firestone Butte, East Butte, and Quartz Mtn, marking a region shaped by geothermal activity. The area is characterized by its geological depressions, notably The Potholes, which punctuate the high-altitude pine forests. This recent survey documents the modern infrastructure of the forest, specifically the dense concentration of off-highway vehicle routes such as Ohv #64 Trl, Ohv #80 Trl, and Ohv #70 Trl. These trails weave through the township divisions of t21s r15e and t22s r15e, reflecting the contemporary use of the land for motorized recreation within the managed timberlands of the Cascades' eastern slopes.
