Here are two of my favorite spots to visit even though there are no minerals or fossils specifically to find. Although Melanterite has been reported at Kings Tunnel. (Last visit I did see some white crusts on the wall timbers that probably was Melanterite. Not really collectible. I’ll try to take a photo on my next visit later this summer.
