The Antelope Valley is located in northern Los Angeles County, California, United States, and the southeast portion of California's Kern County, and constitutes the western tip of the Mojave Desert. It is situated between the Tehachapi, Sierra Pelona, and the San Gabriel Mountains. The valley was named for the pronghorns that roamed there until they were all eliminated in the 1880s, mostly by hunting, or resettled in other areas.
