American Native culture is deeply ingrained in the area. We had seen similar earthworks in Ohio and West Virginia and these mounds in Georgia were on par with those sites.
The hills were made around 1000AD near the Etowah River as burial sites for Indians of the Mississippian culture that inhabited the land at that time.
The Etowah Park includes several mounds and portions of excavations of a village. There is a museum building with artifacts taken from the mounds and a souvenier shop to get an embossed cup or refrigerator magnet trinket.
A good website about the Native American Culture is given by accessing this: http://www.lostworlds.org/etowah_mounds.html or going to the website listed below.
