Multiproxy evidence from caves of Native Americans altering the overlying landscape during the late Holocene of east-central North America
We compare environmental changes recorded in stalagmites and alluvium from the mountainous Buckeye Creek basin of West Virginia, USA to a nearby, independent archaeological record of Native American presences in the forested watershed. A climatic record constructed from stable isotopic (δ 18 O calc...

We compare environmental changes recorded in stalagmites and alluvium from the mountainous Buckeye Creek basin of West Virginia, USA to a nearby, independent archaeological record of Native American presences in the forested watershed. A climatic record constructed from stable isotopic (δ 18 O calc and δ 13 C calc ) and trace metal (Sr/Ca) ratios in stalagmitic calcite is consistent with regional palynology during much of the Holocene. The stalagmite δ 13 C calc and Sr/Ca values track aridity associated with North Atlantic Ocean (NAO) ice-rafting events during solar minima.
