About this map

The Sierra Madre Mountains and San Rafael Mountains converge in this high-elevation terrain during the early 1940s, marked by the winding course of the Cuyama River. This river corridor serves as the primary boundary between San Luis Obispo and Santa Barbara counties, providing a vital water source in an otherwise arid landscape. The map reveals a network of working livestock operations and remote homesteads, including the Avenales Ranch, Buckhorn Ranch, and Rice Ranch, reflecting the region's enduring ranching economy.
