Santa Ana River hydrology and a dense network of major railroads define this landscape during a period of significant Southern California expansion. The map details the convergence of the Atchison Topeka and Santa Fe, Southern Pacific, and Union Pacific lines as they navigate the valley floor between Slover Mtn and the Box Springs Mountains. Urban growth is visible through the purple-tinted revisions, showing the outward reach of San Bernardino and Riverside into former agricultural lands.
