How do scent smelling dogs measure up to high tech imaging equipment when searching for 200 year old burials? Very well, actually! On January 25, 2016 we followed up a cadaver dog search with a GPR survey of Kettle Creek Battlefield located in Washington, GA. This was the site of a quick, but brutal Revolutionary War battle that took the lives of approximately 80 British and 7 or 8 American soldiers. One idea was that the British were buried in a mass grave, possibly on the southern side of War Hill (the location of the most intense fighting). The cadaver dogs located an area with human remains scent and this was one of the targets that we investigated with GPR. The GPR data, however, indicates that there may only be a single clandestine grave at this spot. There is no indication of a large pit.
During the first phase of this investigation, the dogs also located numerous targets in the battlefield itself. The GPR data also support most of these as probable graves. In every case where a GPR reflection indicative of a possible grave was recorded, the location was slightly uphill from the where the dogs hinted. This is expected since the decomposing residue will travel through the subsurface after the burial is interred.
The power of the Kettle Creek Battlefield study is the high correlation of Human Remains Detection dog targets with GPR reflections of probable burials. This method allowed the project to cover a large area quickly with the dogs from K9 Search & Rescue Specialists, Inc. to identify possible targets, and then evaluate those targets with non-invasive subsurface imaging. The small GPR reflection on the southern side of War Hill coupled with the 6 targets identified in the battlefield (5 supported by the GPR) also might indicate that no mass grave exists. The only way to figure this out would be a full coverage investigation with the dogs, geophysics, and some minimal testing. Thank you to the Kettle Creek Battlefield Association for supporting the project and preserving public history. Stay tuned…
