The Umatilla National Forest and Whitman National Forest converge in this high-country landscape, where the legacy of hydraulic mining is etched into the earth. The North Fork John Day River winds through the southern portion of the quadrangle, flanked by the Klopp Placer Mine and the Thornburg Placer Mine. These sites, along with visible Dredge Tailings further downstream, highlight a period of intensive resource extraction along the riverbanks.
