Malheur Reservoir dominates the northern reaches of this high-desert landscape in Malheur County, where the waters of Willow Creek are impounded before flowing eastward. The terrain is defined by its drainage basins and ridges, including the prominent Reservoir Butte and the elevation of Brogan Hill. To the south, Cow Valley provides a level expanse between the rising peaks, serves as a natural corridor for regional travel.
