Recent geoarchaeological work on relict aeolian deposits in the North Carolina Coastal Plain has shown the potential for understanding prehistoric hunter-gatherer adaptations to changing environmental conditions likely related to Holocene climate change. Archaeological surveys and testing along the Tar River has revealed numerous sites with stratified Early Archaic through Woodland occupations. Geophysical, archeostratigraphic and sedimentological analysis along with chronometric dating OSL and 14C) of source-bordering aeolian sediments along the Tar River in North Carolina indicate dune drapes &sim；1 meter thick) accreted throughout much of the Holocene. Aeolian burial events along the Tar River appear to reflect Holocene millennial-scale climatic cyclicity e.g., Bond Events) and its related effects on the fluvial system. These events likely influenced both hunter-gatherer adaptation and site preservation along the Tar River. Combined radiocarbon and OSL ages from lower paleo-braidplain sites, indicate incision of the lower paleo-braidplain and initiation of dune deposition just before or during the Younger Dryas stadial. The presence of stratified archaeological remains in these sediments preserves a record of both prehistoric human adaptations to local conditions and changes in depositional processes marking large-scale climatic change in the southeastern United States.
