Greenhorn Mountains

The Greenhorn Mountains are a small mountain range located in eastern Oregon, near the border with Idaho. This remote and rugged range rises abruptly from the surrounding high desert, with elevations reaching over 8,000 feet. The terrain is characterized by steep, rocky slopes, narrow canyons, and scattered stands of ponderosa pine and Douglas fir. The Greenhorns are part of the larger Blue Mountain physiographic province, formed by ancient volcanic and tectonic activity. Despite their remote location, the range offers excellent opportunities for outdoor recreation, with scenic backcountry hiking and camping.
