Scouted the area around Joppenbergh Mountain with some people today.
Entered a couple of smaller mines including this adit.

So, if anyone is knowledgeable about locations of old mines, drop me a line, I'd love to chat with you about them. Even better if you have access to any of the mines. One of the things I'm especially interested in doing is tying names to the mines so I can do some historical research.
