About this map

Lake Mathews dominates the central landscape of this Riverside County region, serving as a critical water storage reservoir. The surrounding terrain is defined by dramatic elevation changes, from the heights of Arlington Mtn and Monument Peak to the canyon floor at Cajalco Canyon. Infrastructure supporting the water system is evident in the Cajalco Tunnel and the network of roads serving the developed northern hills, including Victoria Grove Pky and El Sobrante Rd.

South of the reservoir, the map transitions into a more rural and industrial history. The settlements of Arcilla and Temescal sit near the Temescal Wash, an area historically significant for its clay deposits and mineral extraction. To the west, the boundary of the Cleveland National Forest rises into the Santa Ana Mountains near Coldwater Canyon, while the eastern portion is occupied by the broad Gavilan Plateau and Gavilan Peak.
