Originally standing about in height, the platform mound was constructed in 10 stages. Extensive damage through erosion and amateur digging have resulted in only the first four stages to have distinguishable form and purpose, while also decreasing the height of the mound to. Stage 1 of the mound began as a low truncated rectangular pyramid about in height, which was probably used as a dance platform or dias. The fill for this mound came from the midden area of a previous Woodland period settlement; it was followed by a thinner semi-impermeable blue-grey clay cap. Stages 2–6 follow the same pattern. The clay cap had a low rim and trough around the base of the mound and in some cases extended to as much as from the base of the mound. The nature of the impervious clay and the trough to carry away rainwater helped to protect the interior basketloaded fill from erosion. At Stage 2 the mound was across at the base and with a summit roughly square and several feet higher than Stage 1. On top of this mound a structure was added. During these stages, smooth boulders from the river were incorporated into the mound, possibly to help stabilize the shape. Stages 7–10 did not have the clay cap feature and mound construction seems to occur only on the southern and eastern sides of the mound. These stages may have been to add an apron-like extension or ramp out from the main body of the mound.

Burials
There are more than sixty burials at the Chauga site, and more than thirty burials within the mound itself. The mound contains artifacts ranging from stone tools, potsherds and ornaments made of shells, copper plates, rocks and minerals, many of which were deposited as grave goods with the burials. Among the artifacts found at the site is a steatite plate with an anthropozoomorphic human-headed winged figure of a style often associated with the Southeastern Ceremonial Complex.
Excavations
first excavated there in 1953 and he was later followed by Carl Miller in 1958. The most complete excavation took place under the leadership of Arthur R. Kelly and Robert S. Neitzel from August, 1958 to January 1, 1959. Kelly and Nietzel performed salvage archaeology on the site in conjunction with the U.S. National Park Service while working at the University of Georgia with the hope of salvaging as much information as possible before the Hartwell Basin flooded the site.
