I have found a pile of rocks(most the size of cantaloupes) approximately 2 1/2 feet tall, 3 feet in circumference in the woods about 100 yards from an old wagon road. It sits half way up a hill. Any ideas what it could be. Indians were prevalent in the area. It is about 1 mile from one of the first houses in the area. This marker is obviously extremely old. Good deal of moss and lichens. Thanks for any ideas.
