We have a lot of gravel companies around us and I had one test our dirt in various areas to see if it was worth anything to them. They would take their track hoe and dig a deep hole staright down as fast as they could as deep as they could before the hole would get a chance to start collapsing. They would get about 20' down. I would be there and take a look down that hole. I will never get over what I saw. There was literally a fast flowing river coming out one side of the hole and it was leaving the other side just as fast. It was a bit of an eerie feeling.
Does the water in that hole stay cold like spring water?
