Rancho Los Alamos y Agua Caliente was a Mexican land grant in present day Kern County, California given in 1846 by Governor Pio Pico to Francisco Lopes, Luis Jordan and Vicente Botiller. The name means Cottonwoods and Hot Springs Ranch in Spanish. The native riparian Fremont Cottonwood (Populus fremontii) grow around natural springs. Rancho Los Alamos y Agua Caliente lay between two other Mexican Land Grants in the Tehachapi Mountains, Rancho El Tejon and Rancho Castac. The rancho is now a part of the Tejon Ranch.
