These symbols are in a deep canyon and there were several mines in that area. Our family has been trying to make some sense of this and have spent many years wandering back and forth. When we first took the slides we thought they were just a bunch of kids writing- having fun. We put them in our closet and there they stayed for nearly 15 years until my husband got into metal detecting and his friend saw the pictures and said he had a book that some of these symobls. We have Kentworthy's book and think we know what some signs are?? Gary thinks he may have found a hand arrrastra. Any and all opinions welcome. Feel free to e-mail also. [email protected]. Will send some pictures of the rock area as well. Thanks, we need help.
