Studying Variability in the Archaeological Record: An Ethnoarchaeological Model for Distinguishing Mobility Patterns

The identification of mobility patterns is important to issues of demography and sociopolitical organization. The ethnoarchaeological model of mobility discussed here attempts to provide relevant indicators of mobility strategies applicable to prehistoric data. The model provides an understanding of site variability at different scales or levels of mobility. It is possible to infer anticipated and actual mobility patterns by applying knowledge of a combination of site size, presence and number of formal storage facilities or their absence, artifact inventories, and diameter of huts. The model is used to distinguish short seasonal occupations from contemporaneous year-round sedentary occupations among fivevar Mesa Verde Pueblo II sites located in the American Southwest. The ethnoarchaeological model provides an alternative approach for examining regional intersite variability.
