Agricultural Intensification, Regional Differentiation, and Incipient Village Formation: Early Formative Period Patterning in the San Carlos Safford Area, Southeastern Arizona

Archaeologists commonly interpret the Early Formative period through the lens of ceramic technology and as a significant break from Late Archaic or Early Agricultural period lifeways; however, the local changes underlying this pattern often remain obscure. In this paper, we evaluate the existing literature for the Early Formative period the San Carlos Safford Area of southeastern Arizona and discern the accuracy of the current understanding of the local chronology, material culture, and regional patterning. Through a systematic examination of chronological, ceramic, and architectural data, we advocate for several interpretive shifts in the Early Formative period and characterize regional patterning during this temporal interval. We relate the emergence of larger villages as an adaptive strategy against a significant climatic event in the early to mid-sixth century yet also demonstrate the incongruities present between the San Carlos Safford Area and far better studied areas within central and southern Arizona.
