Hello all, I am trying to figure out a way to determine the precise location of prairie dog nest chambers underground so that I can sample soil from the chambers (the chambers may be located above the lowest part of the tunnel, so gravity-based methods may not work). I have tried Electromagnetic Survey but not had success, and have been told that Ground-Penetrating Radar does not work well in clay soils. Does anyone have suggestions on how I might resolve where (laterally and at what depth) the chambers are located? Any ideas are welcome!
