Prehistoric mounds are common from the plains of the Midwest to the Atlantic seaboard, but only in this general area was there a culture that regularly constructed mounds in the shape of mammals, birds, or reptiles. The monument contains 2,526 acres with 195 mounds of which 31 are effigies. The others are conical, linear and compound. Eastern Woodland Indians built mounds from about 500 BC until the early European contact period. Natural features in the monument include forests, tallgrass prairies, wetlands and rivers. The visitor center, located at the park entrance, contains museum exhibits highlighting archaeological and natural specimens, an auditorium and book sales outlet. The park has eleven miles of hiking trails. No roads exist in the park. Rangers give guided hikes and prehistoric tool demonstrations, June 11 through Labor Day weekend. Educational programs are presented on- and off-site by appointment. There are no lodging or camping facilities in the park. Nearest camping is at Pikes Peak State Park and Yellow River State Forest in Iowa and Wyalusing State Park in Wisconsin. Various primitive campgrounds exist in the area as well.
