About this map

The Greenhorn Mountains define the high terrain of this landscape where the Umatilla National Forest and Malheur National Forest meet. This mid-1990s survey illustrates a region shaped by both wilderness conservation and historical resource extraction. The northern portion is dominated by the Vinegar Hill - Indian Rock Scenic Area, while the central valleys trace the hydrological divide between the Middle Fork John Day River and the South Fork John Day River.

Evidence of historical mining is scattered throughout the drainages, notably at the China Diggings Mine and the Stirhum Mine Tunnels, along with smaller prospects like the Reed Mine and Wray Mine. Remote administrative outposts like the Sunshine Guard Station and established campsites such as Squatter Flat provide insight into the Forest Service's management of these high-altitude timber and mineral lands during the late 20th century.
