Mitchell is also the home of the Dakota Discovery Museum, whose mission is to present and preserve the history of the prairie and the people who settled it. The museum covers the time period from 1600, when the Native Americans were still largely undiscovered, to 1939, the end of the Great Depression. The museum holds one of the most complete and pristine collections of American Indian quill and bead-works. The Dakota Discovery Museum also features artists such as Harvey Dunn, James Earle Fraser, Charles Hargens and Oscar Howe. In the village area behind the main building are four authentic historical buildings, including an 1885 one-room school house and the fully furnished 1886 Victorian-Italianate home of the co-founder of the Corn Palace, Louis Beckwith. Two new features of the museum are Discovery Land, a hands-on activity area for children ages five to ten, and the Heritage Gardens Project, which brings indigenous plants to the gardens surrounding the museum and historical buildings.
