1966 Map of Monolith

About this map

The industrial and transit-heavy corridor of the Tehachapi Valley is meticulously detailed in this mid-1960s study, centered on the settlement of Monolith. The landscape is defined by the critical infrastructure of the era, where the Atchison Topeka and Santa Fe and Southern Pacific railroads converge near Eric and Cameron. These rail lines follow the natural grades through Tehachapi Pass alongside early infrastructure like the Los Angeles Aqueduct and numerous high-pressure pipelines. Resource extraction is a primary driver of local development, evidenced by several quarries, a Borrow Pit, and Limestone deposits near the valley floor. To the east, the terrain transitions into the steep ridges of Pajuela Peak and the drainage of Water Canyon Creek, while the ephemeral Proctor Lake occupies the valley's western basin.
