Quaternary landscape evolution, pedology, and geoarchaeology in central Texas.


Central Texas provides a unique environment as a climate ecotone for studying processes of river incision, deposition, and soil formation. This is the first study in central Texas focused on alluvial floodplain and terrace formation of the Brazos and Bosque rivers. Additionally, Buttermilk Creek provides a view of late Quaternary landscape evolution in central Texas along a low-order tributary. The late Quaternary history of central Texas is a complex story of climate and hydrologic changes, sediment supply, and human interaction. From >60 ka near the transition of MIS 5 to 4 to historic times through the end of MIS 1, the stream systems have recorded changes as rivers incised and aggraded.
