Greenhorn stands as a focal point in this high-elevation landscape of the Blue Mountains, straddling the line between Baker and Grant Counties. This mid-1990s survey preserves the footprint of a region defined by its gold mining heritage, marking numerous historical operations such as the Golden Gate Mine, Bonanza Mine, and Humbolt Mine. Evidence of industrial-scale extraction is visible along the watercourses, particularly the extensive Dredge Tailings near Parkerville. The map documents the sites of former settlements like Robinsonville and Tipton, which were once integral to the area's timber and mining economies. Natural features like San Lou Flat and the headwaters of the Burnt River are surrounded by the designated Vinegar Hill-Indian Rock Scenic Area, illustrating the intersection of resource extraction and modern wilderness conservation.
