Rock Eagle was once thought to be as much as 5,000 years old. While there is strong evidence that the area was occupied by Archaic Indians at that time, scholars no longer believe that they created the mound. Current archaeology suggests the mound 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. It is more likely that they represented a unique group. Rock Eagle is the next oldest Indian mound in Georgia after the Sapelo Shell Ring Complex.
