Summary
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology.
The Wakulla Springs site is a well-known paleoindian site in Florida, which contains abundant Pleistocene megafauna and artifacts including early projectile points. Previous optically stimulated luminescence (OSL) dating at the Wakulla Springs Lodge site (8WA329) suggested occupation older than 11.6 ka but younger than 22.5 ka (W.J. Rink et al. Florida Anthropologist 2012) and raised the possibility of a pre-Clovis presence. This work measured luminescence on small aliquots of quartz. This paper extends this work by measuring luminescence on single grains of quartz on several samples from the same site. Bioturbation is an issue, and single grains provide the best resolution for addressing mixing. Methods for interpreting single-grain age distributions are discussed.
