Its Indian GOLD!!!! When Indians were being forced out of Georgia they would bury all their wordly possessions in the ground and mark the spot of the way to it with rock piles and trees bent etc. They did this so the white men wouldnt tale away their gold and they knew that they would one day return to re-calim their treasure, something not many were ever able to do. Ill bet theres a fortune buried near those rock piles!!!!
