March Air Force Base dominates the northeastern corner of this Riverside County landscape, providing a sharp contrast to the surrounding agricultural and mining terrain. The map details a transition from organized military infrastructure and the residential grid of Perris and Val Verde into the rugged elevations of the Gavilan Plateau and Steele Peak. The presence of the Colorado River Aqueduquct cutting across the central hills highlights the critical water management systems required to sustain growth in this part of Southern California.
