Effigy Mounds National Monument

More than 200 earthen mounds are located within the boundaries of Effigy Mounds National Monument. Taking the shapes of a bird, bear, deer, bison, lynx, turtle or panther, these mounds were built 750 to 1,400 years ago for ceremonial purposes. The best way to tour the 2,526-acre park is hiking along the 14 miles of trails that wind their way throughout the landscape. A film at the visitor center provides an excellent introduction.
