DUST CAVE REVISITED: A BAYESIAN REANALYSIS OF THE RADIOCARBON RECORD

Abstract

The Dust Cave cultural chronology and radiocarbon sequence is one of the most important in southeastern North America. In their initial interpretation, the excavators were unable to separate the dates of the early and later strata in ways that facilitate their use for defining the associated cultural components. Here the sequence is reevaluated using Bayesian statistics, one additional date, and assessment of potential outliers. The results produce a useable sequence of non-overlapping cultural components (within the uncertainties of radiocarbon dating) that will improve our understanding the Paleoindian and Early and Middle Archaic cultural chronology in the Southeast.
