We got to get our own dirt that had been brought up from the creek bed and it had not had anything added to it. the man who ran the mine helped us and was at our side telling us and showing us what to look for. Afterward he identified and labeled everything we found. He was very knowledgeable and informed us about the history of the mining in the area. We learned alot and had a great time! We visited three mines and this one was the best.
