Southern Pacific rail lines and the heavy transport corridor through the San Gorgonio Pass anchor this mid-century look at Riverside County. The twin anchors of Beaumont and Banning show significant residential expansion, with purple-tinted revisions from 1972 highlighting the post-war growth of suburban tracts and institutional development, such as the San Gorgonio Pass Memorial Hospital. In the surrounding canyons and benches, the landscape remains dedicated to agriculture and public lands, including portions of the San Bernardino National Forest.
