The Ochoco Mountains are a mountain range in central Oregon. The Ochoco Mountains form the western end of the Blue Mountains province. The mountains were formed when Permian Triassic and Jurassic rocks were slowly uplifted by volcanic eruptions to form the Clarno Formation. Today the highest point in the range is Lookout Mountain. The dominant vegetation on the west side of the range is old growth Ponderosa pine; on the east side Western juniper is common.
