About this map

The Temblor Range dominates the eastern horizon of this 1943 survey, marking the rugged boundary between Kern and San Luis Obispo counties. Settlement in this high-desert environment is defined by widely dispersed ranching outposts and family homesteads, including Iverson Ranch, Bledsoe Ranch, and the San Juan Ranch positioned along the intermittent course of San Juan Creek. These family-named landmarks suggest a landscape where land ownership and water access dictated the rhythm of local life during the mid-twentieth century.

A primary corridor of travel follows the base of the mountains, passing through Palo Prieto Canyon toward Grant Lake. Community life centers on the isolated Choice Valley School, a vital social node for the surrounding residents like V A Anderson and F W Grant. The inclusion of high-precision markers from the USC & GS Grant and USC & GS Prieto surveys highlights the importance of this terrain for geodetic control in the California coast ranges.
