This is a rock I found a few months ago in the north Ga. mountains. It has a grove that wraps around the rock from one side to the other. If you notice there's a small grove on the back of the rock thats not broke off. The out side of the rock is worn smooth,like it was used for pounding or grinding.It was laying in a gravel bar in a small creek.
