His recent fieldwork in the Chevelon region of east central Arizona examines changing patterns of ritual, social relationships, and exchange ties during the 11th, 12th, and 13th centuries. Evidence for significant social conflict in the 11th and 12th centuries appears a century or more before similar patterns become common in the northern Southwest and has been a particular focus of his fieldwork. Continued surveys and excavations in the Chevelon region are planned for the next several years.
