Skylark Ranch and the vital desert water source of Hayfield Spring define this remote stretch of Riverside County. The landscape is a study in 20th-century water engineering, dominated by the massive Colorado River Aqueduct and the nearby Hayfield Lake. These infrastructure projects transformed the arid region, supported by subterranean features like the West Eagle Mountain Tunnel.
