Joshua Tree National Park spans the northern portion of this Riverside County landscape, where the southern reaches of the Eagle Mountains meet the desert floor. The vital infrastructure of the Colorado River Aqueduct is a dominant feature, cutting across the terrain and disappearing into specialized engineering works like Hayfield Tunnel Number One and Hayfield Tunnel Number Two. This industrial corridor supports the settlement at Hayfield, positioned near the Julian Hinds Pump Plant Airstrip.
