Project Description
Project Description
The EUSEG project seeks to evaluate the proposal that late Pleistocene-Holocene eolian, or wind-blown, deposits blanket currently undocumented portions of the archaeological record. Although long recognized in coastal settings, the potential that inland eolian deposits cover <14.5 ka yr old archaeological sites is underappreciated and poorly studied in the Midwestern U.S.
In a recent review of published <14.5 ka yrs old eolian deposits from Indiana, Michigan, Ohio, and Wisconsin, Purtill documented 143 optically stimulated luminescence and radiocarbon ages from eolian deposits younger than 14.5 ka. This suggests that eolian deposits may cover archaeological sites of any age from Paleoindian to Late Prehistoric. Because eolian deposition occurs in low-energy environments, buried archaeological sites may retain especially good integrity.
