Our research in northwestern Chihuahua focused on the area around the famous and important site of Paquimé (or Casas Grandes), which was most influential during the Medio Period, AD 1200–1450 (give or take a few decades either way). Over the past two decades, we directed multiple field projects in the region. At first, we conducted surveys, systematically walking over an area to record whatever archaeological remains were observable. Then we transitioned to the excavation of a range of sites in an attempt to understand how the Paquimé-dominated society was organized and when it dated to, among other questions.
