Round Valley and the Round Valley Indian Reservation dominate the southwestern corner of this survey, anchored by the settlement of Covelo. This high-altitude mountain valley provides a sharp contrast to the surrounding terrain of the California National Forest, which is defined by a dense network of ridges such as Bean Ridge and Anthony Ridge. The Middle Fork Eel River and Black Butte River cut deep through these ranges, creating a landscape that necessitated early remote outposts like the Osborn Ranger Sta and Montague Ranger Sta.
