The Anasazi Abandonment of the San Juan Drainage and the Numic Expansion

Abstract

The nature of the Numic expansion into the southwestern United States, the fortified nature of Pueblo III Anasazi sites, and the close temporal correspondence between the expansion of Numic speakers and the Anasazi abandonment of the San Juan River drainage by 1300 AD lead to the interpretation that population relocations in late prehistoric times were precipitated by Southern Paiute and Ute activities.
