Archaeo-Geophysical Associates, LLC conducted GPR, Gradiometery, and Resistivity at the Hack Hatcher Cemetery. Historic Grave delineation is one of the more difficult targets to identify using geophysics. At 40WM338 geophysics, mostly GPR, aided archaeologists from Weaver & Associates, LLC in their manual excavations at the site. Here geophysics helped limit the amount of excavation that was required.
