A museum on wheels is planning a stop at a local festival this weekend. The University of Iowa Mobile Museum will be parked at the Riverside History Center on Saturday during Trek Fest. The museum features exhibits that explore three different eras in Iowa’s history that span from the last ice age to the writing of the state’s constitution. The Cornerstones exhibit focuses on the founding of Iowa, the Old Capitol building and the creation of the University of Iowa. The museum will be open from 11am to 6pm.
