The Greenhorn Mountains define the high country of this region, where the legacy of hard-rock mining is etched into the terrain. Rising above the Middle Fork John Day River, the area is punctuated by historical mining claims including the Portland Mine, Ben Harrison Mine, and Morning Mine. These sites, along with the Bimetallic Mine and Tiger Mine, indicate a history of extensive mineral exploration and extraction in the high-elevation basins of the Vinegar Hill vicinity.
