If you're visiting Bisbee, there are two must-dos. One is the Copper Queen Mine Tour, and the other is this museum. The entrance is a bit steep considering the size of the place, but the displays are top quality, including the recently-arrived minerals exhibit, which came from the Smithsonian. The top floor, which holds the minerals, felt more like an advertisement for the copper mining industry than a museum, but the first floor is a treasure trove of history and insight into the life of Bisbee.
