It runs through desert and mountain country, from the western Chihuahuan Desert by New Mexico through a zone of grassland and oak-covered hills to the classic Sonoran Desert west of Nogales. The land gets more and more arid as one travels west, and the western third of the border is essentially devoid of human habitation. It is this stretch of the border, once a major road to the Colorado River, that has earned and kept the title El Camino del Diablo, "The Devil's Highway."</span>
