Prado Dam and the Santa Ana River serve as the geographic anchor for this region where San Bernardino, Riverside, and Orange counties converge. The landscape is defined by the sharp transition from the residential and industrial growth of Ontario, Chino, and Corona into the preserved open space of Chino Hills. In the north, the community of Los Serranos and the private school Boys Republic sit near the edge of the more developed Chino basin.
