[PWAX: A couple choice quotes are:
"Common to cultures across the globe, cairns are manmade structures that range from loose stone piles to carefully built towers. They were erected by ancient peoples to indicate sites of special events, such as battles. They were also used for navigation and astronomical observations, as well as for burial markers. Today cairns are commonly used by hikers as trail markers and can be found along well-traveled routes like the Appalachian Trail." - looks just a wee bit plagiarized but thanks anyway.
"There is no doubt in my mind that this is going to turn out to be the most significant site in the state of West Virginia," he says. "There isn't anything that approaches it."
Does anyone else think this is like the California walls?
