The Chaco Anasazi: Sociopolitical Evolution in the Prehistoric SouthwestHardcover, 30 October 1992

In the tenth century AD, a remarkable cultural development took place in the harsh and forbidding San Juan Basin of northwestern New Mexico. From small-scale, simply organized, prehistoric Pueblo societies, a complex and socially differentiated political system emerged that has become known as the Chaco Phenomenon. This study combines information on political evolution with archaeological data to produce a sociopolitically based model of the rise, florescence, and decline of the Chaco Phenomenon.
