The Lost World of the Old Ones: Discoveries in the Ancient Southwest (Paperback) (ISBN-13: 9780393352337)

In this thrilling story of intellectual and archaeological discovery, David Roberts recounts his last twenty years of far-flung exploits in search of spectacular prehistoric ruins and rock art panels known to very few modern travelers. His adventures range across Utah, Arizona, New Mexico, and southwestern Colorado, and illuminate the mysteries of the Ancestral Puebloans and their contemporary neighbors the Mogollon and Fremont, as well as of the more recent Navajo and Comanche.
