Here are the results of the gradiometry on those three grids:



Now compare the gradiometry with the resistivity:



Very curious.  Some similar hot spots, particularly in the western third.  I have a feeling that’s a part of the drainage system that helps to keep the field dry, but I could be wrong.  Going up the middle of the gradiometry there is a power line I think (yeah, we might want to stay away from that!).  The area to the east on the resistivity that looks like a right angle corner shows up as something in the gradiometry…that actually might be an interesting place to look.  But there is also the area smack dab in the middle, that is low resistivity, low gradiometry.  I think this might be interesting because it does not look like we will hit much building material there.
