Mining operations and industrial infrastructure define this high-country landscape within the Tahoe National Forest during the mid-twentieth century. The deep canyons of the North Fork American River are marked by numerous historic claims, including the Rawhide Mine, Blackhawk Mine, and the American Eagle Mine. An extensive network of tunnels, such as the Golden River Tunnel and Cape Horn Tunnel, suggests the scale of underground exploration along the Forest Hill Divide.
