Sunday, Sepember 12th, 2010 Neil Anderson and his team of students performed a Ground Penetrating Radar survey of the Pulaski County Poor Farm.
The purpose of this testing is to allow us to know the exact location of each grave in the cemetery, as well as how many burials were performed here. Local folklore has estimated the number of burials somewhere between 100-150.
Ground Penetrating Radar (GPR) uses a high frequency radio signal that is transmitted into the ground and reflected signals are returned to the receiver and stored on digital media. The computer measures the time taken for a pulse to travel to and from the target which indicates its depth and location. The reflected signals are interpreted by the system and displayed on the unit’s LCD panel.
In addition to the GPR survey that was done, Mr. Anderson and his team plan to return to perform electrical resistivity tomography testing. This procedure is very time consuming and will only be performed in specific sections of the cemetery.
The team collected extensive data and it will take 2-3 weeks for them analyze their findings.
The video below was created by the Florida Public Archaeology Network and shows examples of GPR technology at work in cemeteries.
