The Deschutes River carves the western boundary of this high-desert landscape where the borders of Sherman Co and Wasco Co meet. The terrain is defined by a dense network of drainage systems, including Harris Canyon, Bull Run Canyon, and Grass Valley Canyon, which illustrate the complex topography of the plateau. Near the settlement of Erskine, the land transitions from the deep river breaks to agricultural and grazing lands, supported by water features like Powell Reservoir and Sheep Springs.
