About this map

Patriquin Quicksilver Mine and the Kings Quicksilver Mine highlight the industrial activity in the northern ranges during the early twentieth century. This survey documents a landscape of rugged canyons and isolated ranches where the Diablo Range and Temblor Range converge. The southern portion shows the emergence of infrastructure such as the Shandon Pumping Sta and the Paso Robles Road, which connected early settlements like Shandon and Annette to the larger agricultural networks of the Central Valley.

Rural life is anchored by family-named landmarks and small educational outposts, including Melville School, Eagle School, and Choice Valley School. Large holdings like Cholame Ranch and Sacramento Ranch define the land use, while the arid terrain is carved by the Cholame Creek and San Juan Creek drainages. The map records the complex political geography where five counties meet, tracing the Boundary Line across the Cholame Hills and the dry expanse of the Kettleman Plain.
