1967 Map of El Casco

About this map

San Timoteo Canyon serves as a primary corridor for the Southern Pacific railroad, cutting through a landscape defined by the erosive ridges of The Badlands and the open San Jacinto Valley. In this mid-century period, the map documents a shift from traditional rural uses toward suburban development near Calimesa and Yucaipa. Historical landmarks like Eden Hot Springs at the foot of Mt Eden reflect the area's legacy as a destination, while the small settlement at El Casco and its nearby El Casco Lake anchor the northwestern portion of the canyon. Significant land divisions, including the Tract Between San Jacinto and San Gorgonio and various Grant Boundaries, illustrate the complex transition from historic rancho holdings to modernized property lines in Riverside County.
