A wonderfully quirky museum located on a row of false-fronted buildings that looks like a Dodge City movie set, with evocative exhibits on the area's pioneer past and its Japanese and Chinese communities. There's also a walk-through mine tunnel that offers a glimpse of just how tough the job would have been (the frightening iron lung exhibited upstairs does the same).
