Santa Catarina Spring and the surrounding desert canyons define this 2012 survey of the San Diego County backcountry. The map traces the rugged convergence of several watercourses, including Indian Cr and Coyote Cr, which have carved out notable landmarks like Middle Fork Borrego Palm Canyon and the Valley of the Thousand Springs. Human settlement is clustered toward the southeast, where residential developments and the Borrego Palms Resort sit at the base of the mountains.
