The book is a substantially revised and expanded overview of the legacy of prehistoric cultures of the American Southwest, as preserved and interpreted by the National Park Service in more than 37 sites. The DVD explores the monumental architecture and finely crafted arts created by the ancestral culture of the Southwest while telling how explorers, ranchers, and scholars pieced together the history of these ancient Indians. The DVD features menu-based chapter selections, English language subtitle option, and a transcript of the narration in a DVD-ROM content area for computer users.--From publisher.
