Effigy Mounds National Monument preserves more than 200 prehistoric mounds built by pre-Columbian Mound Builder cultures, mostly in the first millennium CE, during the later part of the Woodland period of pre-Columbian North America. Numerous effigy mounds are shaped like animals, including bears and birds.
The monument is located primarily in Allamakee County, Iowa, with a small part in Clayton County, Iowa, in the midwestern United States. The park's visitor center is located in Harpers Ferry, Iowa, just north of Marquette. In 2017, the Effigy Mounds were featured in the America the Beautiful Quarters Program.
