The history of the local plains and the state of Montana are the main focus of Billings, Montana's, Yellowstone County Museum. Visitors come from far and wide to view rare exhibitions and artefacts that reflect not only human history in the state and plains, but the diverse wildlife that lives there.

Prehistory and mid-twentieth century history abound in the Yellowstone County Museum. Every culture that has touched the state, including its prehistoric peoples and animals, as well as more modern peoples are portrayed through varied archives, exhibitions and collections. These include personal items, household items, textiles, music, medical items, military memorabilia, transportation devices, sheep/cattle herding, mining, the Westernization of the state and local and ancient tribes.

The museum is open from February through December, from Tuesdays to Saturdays, from 10:30am to 5:30pm. Admission is free, though donations are gratefully accepted.
