This study examines aspects of movement and mobility of hunter-gatherer groups in the east central Great Plains during the Middle Holocene, between 8500 cal and 5000 cal B.P. Few published reports detail archaeological assemblages or address features of prehistoric mobility in this subregion of the Great Plains. Current research on the Great Plains emphasizes bison procurement and low regional bison mobility. This thesis presents interpretations of hunter-gatherer mobility based on examination of chipped stone assemblages from two Middle Holocene archaeological deposits (the Hill and Simonsen sites) in western Iowa. The resulting analysis demonstrates restricted hunter-gatherer mobility within this subregion, with similar geographic range to that reported for Middle Holocene bison herds.
