Paleoseismology at Old Town Ridge

Summary

This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology.

In the fall of 2018 personnel from the Arkansas Archeological Survey, University of Memphis, and the Natural and Cultural Resources Services conducted investigations at Old Town Ridge (3CG41) to determine if Mississippian period Native Americans abandoned the site circa A.D.1400 because of earthquake activity. Excavation of Trench A exposed four sediment deposits, a cultural deposit, and a plowzone. The sediment deposits include a pre-liquefaction alluvial deposit and three separate sand dikes and associated sand blows. The cultural deposit consists of an anthropogenic refuse-rich soil that post-dates the alluvium and pre-dates the sand dikes. Sand venting caused vertical displacement of the cultural horizon across the vent zone. This presentation briefly describes the field methods, radiocarbon assays, and preliminary interpretations of cultural features and natural transforms in Trench A.
