Rock Eagle Effigy Mound is an archaeological site in Putnam County, Georgia, U.S. estimated to have been constructed 1,000 to 3,000 years ago. The earthwork was built up of thousands of pieces of quartzite laid in the mounded shape of a large bird (102 ft long from head to tail, and 120 ft wide from wing tip to wing tip). Although it is most often referred to as an eagle, scholars do not know exactly what type of bird the original builders intended to portray. It is listed on the National Register of Historic Places (NRHP) because of its significance. The University of Georgia administers the site.
