About this map

Greenhorn stands as a focal point in this mountainous region where the borders of Grant and Baker counties meet. The landscape is defined by an intensive history of extraction, evidenced by the numerous mining claims dotting the slopes, including the IXL Mine, Bonanza Mine, and the Humboldt Mine. These operations were supported by complex water systems like the Orofino Ditch and McWillis Ditch, which redirected mountain streams to support hydraulic or milling processes.

Evidence of earlier settlement patterns is found at several former town sites such as Robinsonville and Parkerville. The winding Old Railroad Grade near Tipton follows the natural corridor of the North Fork Burnt River, illustrating how the timber and mining economies dictated the path of infrastructure through the Whitman National Forest. Placer mining remains visible through the Dredge Tailings mapped along Olive Creek and the riverbanks.
