Kendrick Frazier, People of Chaco: A Canyon and its Culture (W.W. Norton & Co., 1988).
Chaco Canyon, in northwestern New Mexico, was the home to the Chacoan Anasazi, who built roads and multistory dwellings and then suddenly decamped, leaving us the ruins of their efforts. This is a thorough and readable account of the canyon’s ancient inhabitants and what archeologists have figured out about their lives. Since I read it, the book has been updated in a new edition.
Here is Frazier’s Wikipedia page. Here is Google Book Search. JSTOR has a review from the Journal of Anthropological Research if you have privileges (I don’t). Many sites about Chaco Canyon recommend the book, including some that follow. Here is the National Park Service’s Chaco Canyon site. Here is the text of a park brochure with a wealth of information. Christopher H. Sterling offers all sorts of good links; he calls this book the place to start. Minnesota State provides extensive information about Chaco Canyon. Mark Justice Hinton’s site has all sorts of interesting stuff, including a wealth of links, but some of them seem to have expired, including the one to a review of Frazier’s book.
