Effigy Mounds National Monument preserves more than 200 prehistoric mounds built by Native Americans including numerous effigy mounds shaped like animals, including bears and birds. It is located in Allamakee County and Clayton County, Iowa in the midwestern United States.
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 14 miles of hiking trails. No paved public automobile access roads exist in the park. Rangers give guided hikes and prehistoric tool demonstrations that are scheduled and advertised, mid-June through Labor Day weekend. Educational programs are presented on- and off-site by appointment.
Natural features in the monument include forests, tallgrass prairies, wetlands and rivers. There are no lodging or camping facilities in the park. Excellent camping is available at nearby Pikes Peak State Park and Yellow River State Forest in Iowa; there is also Wyalusing State Park in Wisconsin. Various primitive campgrounds exist in the area as well. The national monument is quite close to the town of Marquette, Iowa, and is just across the Mississippi River from the city of Prairie du Chien, Wisconsin, where ample motel and gambling-boat facilities exist.
