About this map

The southern portion of Corona meets the steep northern slopes of the Santa Ana Mountains in this modern topographic study. The landscape is defined by the transition from dense residential and commercial development in settlements like El Cerrito and Pepper Corner to the protected wilderness of the Cleveland National Forest. Infrastructure including the Riverside Canal and the Oak Street Reservoir underscores the region's managed water network, while the intricate system of drainages such as Temescal Wash, Bedford Wash, and Wardlow Wash illustrates the natural hydrology flowing toward the Temescal Valley.

Higher elevations reveal a network of fire roads and trails, including the Bedford Motor Way and Silverado Motor Way, which provide access to peaks like Pleasants Peak and Bedford Peak. These routes trace the ridges above deep-cut terrain features like Tin Mine Canyon and Hagador Canyon. The map also captures the Riverside Co Orange Co boundary as it crests the mountain range, separating the suburban sprawl of the inland valley from the more isolated reaches of Ladd Canyon and Silverado Cr.
