The Ochoco National Forest dominates this landscape, where volcanic geology and high-desert water sources define the terrain. Named lava flows like Peterson Lava, Broadway Lava, and Jones Lava mark the high country of the Ochoco Mountains, indicating the volcanic history of central Oregon. The map reveals a complex network of forest development roads, including Peterson Point Rd and Summit Rd, which provide access to high-elevation points like Peterson Point and Black Mtn.
