Boundary theory as a means to understanding social space in archaeological sites

Social space in archaeological sites is constructed and produced by differentiation in behavior (habitus) and is characterized by domains or activity areas separated by boundaries. Activity areas vary in their flexibility and permeability to intrusion of other activities. This is reflected in the nature of the boundaries between activity areas. A study of boundaries, archaeologically often represented by transitional space, can provide insight into human behavior, the use and construction of space, and the contemporaneity of activities represented in a site occupation. It is suggested that kill site activities such as primary butchering may have relatively inflexible and impermeable boundaries, that activities such as tool resharpening may be more flexible, and that secondary processing may be more permeable to the intrusion of other activities. A study of a selection of activity areas at Head-Smashed-In Buffalo Jump confirms that these concepts do enhance our understanding of site activity areas and that an examination of boundaries can allow an assessment of activity area contemporaneity.
