An engaging portrait of the Chaco Anasazi, an agricultural society which at the height of its power in the 11th century dominated much of the four corners region With maps, black-and-white photographs, extensive notes and bibliography. David Stuart, whose course on Ancient Mexico was the inspiration for this book, is a provocative, thoughtful guide to the development -- and eventual collapse -- of Chaco society. Highly recommended for visitors to Chaco Canyon and other mesa sites in Southwest.  (USW228, $24.95)
