1959 Map of Juniper Hills

About this map

Juniper Hills and Cima Mesa sit at the transition between the high Mojave Desert and the steep northern slopes of the San Gabriel Mountains during the late 1950s. The landscape is defined by the massive tectonic scar of the San Andreas Rift Zone, which runs northwest-to-southeast across the sheet, separating the lower alluvial plains from the high-elevation peaks of the Angeles National Forest. To the south, the topography rises sharply toward Will Thrall Peak and Pallett Mtn, cut by deep drainages like John Bird Canyon and Miller Canyon. The map documents a rural foothill community relying on a network of dirt roads and truck trails, such as the Indian Blue Truck Trail, to navigate the complex terrain. Water management is evident through numerous labeled wells and the course of Little Rock Creek as it exits the mountains. Historical travel routes are marked by the Fort Tejon Road, reflecting the era's regional connectivity.
