Most models of Folsom adaptation consider specialized bison hunting and high rates of residential mobility to be defining characteristics. We use spatial and assemblage content data from a sample of 619 Folsom sites located throughout the Great Plains, Rocky Mountains, and Southwest to evaluate whether the archaeological record actually reflects these characteristics. Three spatial scales of analysis are utilized. First, site scale analysis of a subset of sites shows a great deal of variability in spatial and temporal characteristics. Sites can be roughly divided into small, single occupation locales and large, serially occupied sites. Second, day-to-day foraging occurs at what we term the foraging scale. This intermediate spatial scale is poorly understood for Folsom groups, though large sites such as Blackwater Draw and Lindenmeier provide clues that are supplemented by information from the ethnographic record. Third, the macro-regional scale analysis utilizes the entire site sample and indicates that the Folsom archaeological record consists primarily of small locales scattered across the landscape punctuated by only a few large, serially occupied sites. Overall, our analysis suggests that Folsom adaptive systems were more variable than normally recognized, and, in certain settings, may have been characterized by reduced residential mobility. Furthermore, we postulate that Folsom land use, rather than being conditioned primarily by mobile prey, may have been at least partly conditioned by more predictable resources such as wood, water, and toolstone.
