About this map

San Timoteo Canyon serves as a primary corridor for the Southern Pacific railroad during the early 1950s, cutting through the complex topography of the Tract Between San Jacinto and San Gorgonio. This region is defined by the transition from the developing settlements of Yucaipa and Calimesa in the north to the erosion-sculpted terrain of The Badlands further south.

Remote locations such as Eden Hot Springs and the railroad sidings at Hinda and Nicklin highlight the era's reliance on the rail line and local springs. The map documents early aviation infrastructure with the Calimesa Airport and the technical details of water management, including several reservoirs and a Spillway 1946 near El Casco Lake. The landscape reflects a mix of citrus-heavy agriculture, scattered ranching, and infrastructure like the Radio Relay Station and numerous pipelines crossing the hills.
