About this map

Lake Mathews dominates this portion of Riverside County, serving as the terminal reservoir for the Colorado R Aqueduct. The landscape is a study in topographic extremes, transitioning from the developed neighborhoods of Corona and El Sobrante into the steep rises of Arlington Mtn and Estelle Mtn. Below the reservoir, the Cajalco Tunnel and Cajalco Canyon mark the sophisticated water infrastructure required for the region's growth.

To the southwest, the corridor along the Temescal Wash includes the settlements of Arcilla and Temescal Valley, where the terrain meets the northern edge of the Cleveland National Forest. Traces of the area's rural and industrial character remain in labels such as Tin Mine Rd and the small siding of Weisel. The map provides a detailed view of the winding canyon roads and peaks, including Monument Peak and Gavilan Peak, that define the local skyline.
