The Devil’s Highway—El Camino del Diablo—crosses hundreds of miles and thousands of years of Arizona and Southwest history. This heritage trail follows a torturous route along the U.S. Mexico border through a lonely landscape of cactus, desert flats, drifting sand dunes, ancient lava flows, and searing summer heat. The most famous waterhole along the way is Tinajas Altas, or High Tanks, a series of natural rock basins that are among the few reliable sources of water in this notoriously parched region.

Now an expert cast of authors describes, narrates, and explains the human and natural history of this special place in a thorough and readable account. Addressing the latest archaeological and historical findings, they reveal why Tinajas Altas was so important and how it related to other waterholes in the arid borderlands. Readers can feel like pioneers, following in the footsteps of early Native Americans, Spanish priests and soldiers, gold seekers and borderland explorers, tourists, and scholars.

Combining authoritative writing with a rich array of more than 180 illustrations and maps as well as detailed appendixes providing up-to-date information on the wildlife and plants that live in the area, Last Water on the Devil’s Highway allows readers to uncover the secrets of this fascinating place, revealing why it still attracts intrepid tourists and campers today.

"The authors expertly collaborate in documenting this strangely beautiful but inhospitable area of the Sonoran Desert, a place unlike any in the world."—New Mexico Historical Review
