Trade, migration and movement at Cerro de Trincheras, Sonora, Mexico

Summary

Archaeologists study the movement of potters, materials and techniques to understand migration and exchange on both a local and regional scale. Modern international divisions, such as the Mexican- US border, interrupt these research questions in the Greater Southwest culture area. In Sonora, archaeologists have clear evidence of population upheaval after AD 1300; Southern Arizona Hohokam groups migrated into the Altar Valley, bringing with them new ceramic technologies and displacing a resident Trincheras population to the Middle Magdalena valley. Whereas the presence of large amounts of Hohokam Sells Plain ceramics at Cerro de Trincheras in the Middle Magdalena valley suggests that Trincheras and Hohokam populations interacted, neither how the process occurred, nor the impact of those linkages are understood. What processes resulted in such a large percentage of ‘foreign’ plainware ceramics at Cerro de Trincheras? My paper will use ceramic petrography and GIS analysis to address the likelihood of trade, community migration, and the movement of women as part of a wider question of population interaction and innovation in the late prehistoric Greater Southwest.
