Persistent land use patterns and the mid-Holocene housepits of Wyoming

The cyclical use of sites and locales over decades, centuries, and even millennia is an important aspect of hunter-gatherer land use that is rarely considered in studies that focus on a single annual cycle. The long-term perspective provided by archaeological data can be used to delineate persistent land use patterns and contribute to an understanding of the complexity of hunter-gatherer behavior. Mid-Holocene Wyoming housepit data document persistent land use over at least a 2000-year period at three spatial scales-the reuse of housepits, reuse of sites containing housepits, and use of different sites within the larger region. Slab-lined cylindrical basins at many sites in southwest Wyoming provide evidence for stable long-term land use during the middle Holocene. The focal point of this pattern was probably a predictable resource, possibly some type of root plant that would have been available during the dry middle Holocene.
