Combining Trade Good and Radiocarbon Dates Across a Calibration Curve Inversion: Middle Grant Creek

Summary

This is an abstract from the "SAA 2024: Individual Abstracts" session, at the 89th annual meeting of the Society for American Archaeology.

Precise dating of archaeological sites created during the last millennium often benefit from chronological information provided by trade goods but may be hampered by inversions in the radiocarbon calibration curve. Middle Grant Creek is one such site. It is a protohistoric Native American site near present-day Chicago which has yielded a number of European trade goods and for which a series of radiocarbon dates span a large calibration inversion. We created a series of OxCal models that start with the radiocarbon data and progressively incorporate stratigraphic and trade good chronological data. The results provide insight into how OxCal modeling responds as more information is added–particularly with respect to boundary conditions–as well as a better understanding of Middle Grant Creek's chronology.
