Beaumont and Banning anchor this mid-century topographic study of the San Gorgonio Pass, a critical transit corridor shaped by the Southern Pacific railroad. The map documents a period of suburban expansion into the foothills, with purple-tinted revisions highlighting growth around Cherry Valley and the northern reaches of both primary towns. The landscape is defined by the sharp transition from the residential blocks of Banning to the steep slopes of the Banning Bench and the San Bernardino National Forest. Local institutional history is well-represented, from the St Boniface School near the eastern edge to the San Gorgonio Pass Memorial Hospital and several schools serving the post-war population. Significant open spaces like the Morongo Indian Res and Bogart County Park illustrate the geographic complexity of this mountain-flanked valley.
