Bonita and the broad expanses of Cow Valley define this high-desert landscape in Malheur County, where water management and ranching roads have long shaped the pattern of settlement. The northern portion of the map is dominated by the Ironside Valley, where Willow Creek and the engineered Rutherford Ditch reflect a history of irrigation in an arid environment. Topographical landmarks like Cow Valley Butte, Saddle Butte, and Worsham Butte provide distinct navigational points across the high country.
