Triple Spring Obsidian Mine

Tailored for intermediate off-roaders seeking a short but rugged high-desert adventure, the Triple Spring Obsidian Mine trail stands out for its steep, rocky terrain and direct access to a historic volcanic glass source. This 0.85-mile route begins with a relatively gentle grade before climbing through a narrow draw in Oregon's Harney Basin, rising from 4,775 feet to a peak elevation of 5,122 feet. The track demands careful tire placement as the surface is heavily littered with large, razor-sharp pieces of obsidian, making 10-ply tires and a full-size spare essential for any vehicle attempting the climb. Historically utilized to access the mine, the trail offers a fascinating look at a geological site where volcanic glass was sourced for making arrowheads and other tools. Visitors who keep a close eye on the ground may even discover rare green obsidian mixed among the typical dark rocks. Reaching the end of the trail rewards drivers with expansive, panoramic views of Mud Ridge and the surrounding Harney Basin. For those looking to extend their stay, several primitive campsites are located along the route, offering quiet spots to camp under the desert sky.
