The Santa Clara River corridor defines the southern portion of this landscape, where the San Martinez Grande Canyon and San Martinez Chiquito Canyon converge near the settlement of Del Valle. The terrain is characterized by a dense network of drainages and ridges, including the prominent Oak Ridge and several named canyons such as Holser Canyon, Potrero Canyon, and Tapo Canyon. In the northwest, the edge of Lake Piru is visible, marking a significant water feature near the boundary between Los Angeles County and Ventura County.
