The John Day Wild and Scenic River defines the northwestern boundary of this high desert landscape, cutting through the basalt plateaus of the Columbia River Basin. This 2024 map documents a deeply dissected terrain characterized by numerous canyons and draws that funnel toward the river valley. The eponymous Devils Backbone ridge stands as a prominent topographical feature between Sixmile Canyon and the surrounding draws.
