The property was sold to the United States government during this time by Florence Scott. In association with the University of Georgia, the Works Progress Administration (WPA) constructed a granite tower at the foot of the effigy. This made an "aerial" view of the site possible for visitors. In 1954 Kelly reported that both Rock Eagle and Rock Hawk showed indications of having been enclosed by a wall of material similar to the rocks used to construct the effigies. This, perhaps, associates them with the builders of similar walls at Stone Mountain (destroyed, 1923) and Fort Mountain (still standing). An extensive renovation was completed on this site, removing plants from the mound and replacing rocks that were scattered nearby. The mound rises 10 feet above ground level and consists of thousands of small to medium-size rocks.
