CRAIG CHILDS is known for following ancient migration routes on foot, following lines of pre-Columbian trade the Southwest, and, most recently, ways used by the first people to enter the Americas in the Ice Age. He has published more than a dozen books of adventure, wilderness, and science. His new book, Atlas of a Lost World: Travels in Ice Age America, examines the dynamics of people moving into an uninhabited hemisphere in the late Pleistocene, arrivals from Alaska to Florida to southern Chile. He has won the Orion Book Award and has twice won the Sigurd F. Olson Nature Writing Award, the Galen Rowell Art of Adventure Award, and the Spirit of the West Award for his body of work. He is contributing editor at Adventure Journal Quarterly, and his writing has appeared in the New York Times, Los Angeles Times, Men's Journal, and Outside. The New York Times says "Childs's feats of asceticism are nothing if not awe inspiring: he's a modern-day desert father." He has a BA in Journalism from CU Boulder with a minor in Women's Studies, and from Prescott College, an MA in Desert Studies. An occasional commentator for NPR’s Morning Edition, he has taught writing at University of Alaska in Anchorage and the Mountainview MFA at Southern New Hampshire University. He lives outside of Norwood, CO.
