exists to discover and tell the stories of this unique place.

The underground story is both human and geological. The human story revolves around the miners and is connected to all aspects of their lives. The geological story began in an era when the core of the earth "bled" mineral wealth into the fault zones of California. Both aspects of the story are golden.
