The Wyoming Pioneer Memorial Museum occupies a solid building on the State Fairgrounds and does an unusually good job of making frontier history feel specific rather than generic. Established in 1956, it covers the full arc of Wyoming's settlement era: the livestock industry, the Indian Wars, the railroads, and the often-violent clash between large cattle operators and small ranchers that defined the Johnson County War of 1892.
Two floors of exhibits display a wide range of artifacts — Native American pieces including a tepee used in the filming of Dances with Wolves, weapons, domestic objects, and memorabilia from Wyoming's military contributions from the Indian Wars through World War II. Admission is free, which makes it an easy addition to any Douglas itinerary. It is located on the fairgrounds just west of downtown, and the staff are generally happy to discuss the collections in detail.
