What's The Story

Michael Heizer constructed the mounds between 1983 and 1985 as part of a mine reclamation project. He was inspired by effigy mounds constructed by Native Americans during the Late Woodland Period (1400-750 years ago) mostly along the Upper Mississippi River and extending east to Lake Michigan. In Illinois, a few effigy mounds have been found in the Rock River valley. The Effigy Mounds National Monument near Harpers Ferry, Iowa is a destination for those interested in the subject.
