Abstract

Eolian sand dunes and sand sheets of Quaternary age are present at many inland locations throughout the Atlantic Coastal Plain province of the eastern United States. Under modern conditions, this region is not very conducive to widespread eolian sediment mobilization because of a humid and mesothermal climate, relatively low mean surface wind velocities (~1–3 m/sec), and relatively dense vegetation. LiDAR data and optically stimulated luminescence (OSL) ages, however, reveal the presence of widespread eolian sands that were active episodically from ~92– 5 thousand years ago (ka), and that have subsequently been stabilized and degraded by vegetation and pedogenic processes. Most OSL ages from these sands are approximately coincident with the last glacial maximum (LGM), when conditions were much colder, drier, and windier.
