Take a step back in time to the early days of De Smet area residents. The current depot was built in 1906 after a fire on April 23, 1905 destroyed the original one. Pa Ingalls served at the first depot in De Smet. The museum features many historical artifacts and items. Adjacent to the museum is the school house attended by Harvey Dunn (made famous in his painting “After School”). The museum is open in June, July and August and its hours are 10 a.m.-4 p.m., Monday through Saturday.
