Hunter-gatherer Mobility at the Granberg Site (41BX17), Bexar County, Texas

This thesis examines mobility and subsistence practices of hunter-gatherer groups inhabiting the Granberg site during the Archaic period as reflected in the lithic assemblage recovered from the site. The Granberg site is a Central Texas site located in Bexar County in the Middle Salado watershed. The site includes multiple occupations throughout the Archaic period with significant amount of chipped stone material, burned rock features, and a Late Archaic cemetery, and has been the subject of multiple archaeological investigations. Debitage and lithic tools from selected proveniences dating to the Late, Middle, and Early Archaic periods at the site were examined to identify potential changes in settlement patterns. The chipped stone methodology used in this analysis includes Surovell's (2003, 2012) core reduction index, Sullivan and Rozen's (1985) flake completeness analysis, analysis of the lithic tools following the work of Munoz and others (2011), and color and UV florescence analysis of raw materials. This analysis indicates that mobility shifted from a residential to a more logistical strategy, with increasing ranges, from the Early to the Late Archaic.
