My dad used to own a 600+ acre tract of land near Martinsville, VA. No longer in the family, but something keeps nagging at me. There were random piles of rocks throughout the forest, some near an old roadbed, but many were in difficult terrain, far from roads or trails. Several were high up on sides of hills. No doubt they were all man-made piles. I always assumed the early inhabitants, made these piles to mark boundries. I never dislodged any, nor ever thought to swing a detector near one. Does anyone have other ideas as to what they were? Could they have been indian graves? A woodsman's cache' of supplies, etc? Let me know what you think, I can possibly get permission/access to go back from the new owner. Thanks everyone.
