Your right... It's a 3 acre pond of old drilling mud covered with a 12 ft dirt cap over the top of it still unfenced and not posted. The pond had bentinite last put in it some 15 years ago. At that time it was thought to be 20 ft deep. Then 10 years ago the dirt cap was out over it. I'm always very careful about the USA underground reports to protect me from gas lines,fiber optic,etc,etc but how do you see something like this coming.
