The Hauberg Indian Museum, located in the lodge constructed by the Civilian Conservation Corps in 1934, interprets the culture of the Sauk and Mesquakie. The collection of Dr. John Hauberg, a Rock Island philanthropist, forms the basis of the museum's collection, which features full-size replicas of Sauk winter and summer houses. Dioramas with life-size figures depict activities of the Sauk and Mesquakie people typical of the period 1750 to 1830. Many artifacts, including authentic trade goods, jewelry and domestic items are displayed.
