Rancho San Jacinto y San Gorgonio

Rancho San Jacinto y San Gorgonio (also called Rancho San Timoteo and Rancho Yucaipa) was a 4,440-acre (18.0 km2) Mexican land grant in present-day Riverside County, California given in 1843 by Governor Manuel Micheltorena to James (Santiago) Johnson. At the time of the US Patent, Rancho San Jacinto y San Gorgonio was a part of San Bernardino County. The County of Riverside was created by the California Legislature in 1893 by taking land from both San Bernardino and San Diego Counties. The grant encompassed San Timoteo Canyon.
