Rare (unrecorded) and important promotional map of Southern California, drawn by George Rock and published by Albert G. Thurston of Pasadena, California.
In the north the map extends from the Saugus / Newhall area north of the San Fernando Valley to the High Desert, north of the San Bernardino Mountains. In the south, the map reaches from "Coast Royal," "Arch Beach," Capistrano and Laguna Beach on the coast, to Murrieta, Wildomar, Hemet and San Jacinto. Many early roads are shown (with distances between primary points of interest), along with mountains (with elevations), rivers, towns, mountain trails and other features. Relief is shown with hachures.
A fine early map of Southern California, produced by Rock and Thurstson, who would team up to produce many other commercial maps of Southern California regions between 1909 and 1922, including the first Southern California Road map for the Automobile Club of Southern California, although the present map is far more refined and detailed than Rock's Auto Club maps.
The geographical concept of Southern California was still quite new. The first maps to focus on Southern California as its own geographical region were published in the mid-1880s. This map draws on the concept of the Los Angeles Basin, extending to Orange County, the "Inland Empire", San Bernardino Mountains and high desert. The modern conception of Southern California includes San Diego and Imperial Counties, which are geographically separated from the rest by the Santa Ana Mountain Range, which is depicted on the present map.
The present map is extremely rare. We were unable to locate any other examples of the map.
