Abstract
The goal of this project is to identify unmarked burials inside the known limits of a historic cemetery and unmarked slave burials adjacent to the cemetery to answer questions regarding variability in treatment of slaves by slave owners. This project used three geophysical prospection methods (electromagnetic induction/conductivity, ground penetrating radar, and magnetic susceptibility) to image the subsurface and locate unmarked graves. The results indicate that up to 21 possible unmarked graves exist at the Prior Cemetery. The survey detected 17 with two or more geophysical techniques and four with a single technique. Nine possible unmarked graves were tested with a metal probe. Every tested anomaly revealed less compact soils indicative of an unmarked grave.
