The Palo Verde Valley (Spanish: Valle de Palo Verde)[1][2] is located in the Lower Colorado River Valley, next to the eastern border of Southern California with Arizona, United States.[3] It is located on the Colorado Desert within the Sonoran Desert south of the Parker Valley. Most of the valley is in Riverside County, with the southern remainder in Imperial County. La Paz County borders to the east on the Colorado River.
The region is the ancestral home of several Native American tribes: the Quechan, the Chemehuevi and Matxalycadom or Halchidhoma,[4][5] some who have Indian reservations in California and Arizona along the Colorado and Gila Rivers today.
