A guidebook to the ruins of the early Indian cultures, primarily architecture with a few examples of rock art. It is organized by sites, grouped more or less by different cultures; but since more than one culture may have inhabited a particular site, often there is mention of a culture before it has been dealt with in the introduction to a section. The book really needs a general introduction to explain the history of the various cultures before the specific sites are dealt with; there are many maps, but a general map with the areas of all the cultures would have been helpful, as would a timeline. Despite these shortcomings, the book does provide information about the earliest known cultures (Clovis and Archaic), the Mogollon, the Hohokam, the Salado, the inhabitants of the Mesa Verde region, Chaco Canyon, the Kayenta, the Sinagua, the Fremont, and the region around the Rio Grande, and something of their history. It is well illustrated. The author has intentionally limited coverage to well-known publicly accessible sites to avoid encouraging the vandalism which is destroying many of the ancient sites; he is more optimistic about preservation than the second book which I am reading now.
