Ghost Town and Treasure Finds State by State

I have found a very interesting website that is focusing on outdoors activities. Among those activities is prospecting, research, and metal detecting. If you are from Arizona, you certainly have heard about ghost towns and treasure stories. But, have you found a site that is a repository for information about old mining towns (ghost towns) and their locations across America? Not only is the free research and information available, but those selling information are included. The company is out of Washington. It is worth a look.
