Palmdale was first inhabited by Native Americans. Populated by different cultures for an estimated 11,000 years, the Antelope Valley was a trade route for Native Americans traveling from Arizona and New Mexico to California’s coast.Spanish soldier Captain Pedro Fages explored the Antelope Valley in 1772. The opening of California to overland travel through the forbearing desert was due to Captain Juan Bautista de Anza and Father Francisco Garces, a most remarkable Spanish padre. Palmdale is located in Los Angeles County, and the urbanized centers of Palmdale and Los Angeles are separated by the San Gabriel mountain range, which is about 40 miles (64 km) wide. This range forms the southern edge of the Antelope Valley portion of the Mojave Desert. Palmdale is the second-most populous city in the Antelope Valley, and fifth overall in the Mojave Desert, after Las Vegas, Henderson, North Las Vegas, Nevada; and Lancaster.
