This is an ethnoarchaeological study of the settlements of the Raramuri (often known as the Tarahumara), focusing primarily on their mobility strategy. This is important because this groups presents a case where the common equation of agriculturalists = sedentary, and hunter-gatherers = mobile is broken. The Raramuri are agriculturalists with a pattern of mobility between two or more settlements during the course of any year. Graham provides not only a description of this unusual pattern of mobility by a farming group but also a number of insights and suggestions on how archaeologists can detect a mobile lifestyle in the residential areas of prehistoric agriculturalists.
