The settlement of Lonerock sits at the northern edge of this high-plateau landscape, where the deeply carved drainages of Lone Rock Creek and Buttermilk Canyon converge. This 2024 survey documents the rugged transition from the Umatilla National Forest in the south toward the Gilliam and Wheeler county line. The terrain is defined by prominent topographical features like Pine Ridge and Oxhead Ridge, which separate the various forks of the local creek systems. Genealogists and local historians will find the Lost Valley Cem along Lost Valley Rd, a small footprint of early homesteading history in this remote section of Oregon. The map illustrates a network of forest roads and trails, such as the Nat For Dev Rd 060 and Fire Ln, tracing the movement of people and livestock through steep canyons and along high ridges like Oxhead Ridge.
