Rock Hawk Effigy Mound is an archaeological site in Putnam County, Georgia, United States. It consists of thousands of pieces of quartzite laid in the shape of a large bird. Although it is most often referred to as a hawk, scholars do not know exactly what type of bird the original builders intended to portray. Current archaeology suggests that the site was built between 1,000 and 3,000 years ago by Woodland Indians. These Native Americans may have been part of the Adena or Hopewell cultures, although it is more likely that they represented a unique group.
