We did some GPR in a local cemetery. There was one spot that I questioned because it was on the tree line...The GPR guy said no...definitely a body...I’m pretty sure I would be the winner in a dig off.
When I read the article about the GPR survey awhile ago I was taken aback by how it was written. Of course it was a reporter writing it and not the GPR guy. The GPR guy may have said “Anomalies are present in large amounts in this area and may indicate buried bodies, or other objects such as boulders, tree stumps or logs or other types of materials.”
And the reporter stopped at “human bodies”.
An old decayed body, even in a rotted out wooden casket is pretty much impossible to locate. One can locate the disturbed soils sometimes with GPR or other associated objects. Any children that would have died that long ago in a boarding school would probably just have been wrapped in a blanket and laid to rest. Probably no metal associated with such a burial, but sometimes there may be enough metal that using a metal detector helps.
