This 44-acre museum in Butte, Montana, preserves more than a century of American history and brings it to life. Explore more than 50 structures, ranging from the 100-foot-high headframe of the Orphan Girl Mine to a faithful recreation of a mining town, Hell Roarin' Gulch. Half of the displays focus on the cultural and ethnic history of an 1880s to 1920s mining town, while the other half provides you with a detailed look at the history of mining technology. As one of very few museums to occupy an actual historic mine site, they are uniquely able to portray the story of mining from earliest methods to modern techniques.
