Made quite a few hikes around Big Shoal Creek looking for these and finally found them. Story is that they were Native American trail markers. Looking at them in person I do believe they are trail marker stones but believe they are from the Civil War times. Everything on the rocks point you in a direction. One of the turtle points you towards a Bushwhacker hideout.
