Craig Childs is a naturalist, wilderness explorer, and writer known for his work on the American Southwest. Raised in Tempe, Arizona, he holds a B.A. in journalism from the University of Colorado Boulder and an M.A. in Desert Studies from Prescott College, and has spent decades working as a river guide and field instructor across the deserts he writes about. He has published more than a dozen books of science, nature, and personal narrative, and his work has earned the Orion Book Award, the Colorado Book Award, and three Sigurd F. Olson Nature Writing Awards, among others. The Secret Knowledge of Water grew out of his years tracking water through some of the driest terrain in North America, work he later continued in books like House of Rain and Apocalyptic Planet. He lives outside Norwood, Colorado.
