The story of Stone Mountain actually predates both the first white settlers and the Creek Indians before them. At least 12 Archaic Indian sites have been identified in the vicinity of Stone Mountain. Atop the lofty peak prehistoric Woodland Indians (Additional information:Woodland Indians) built a rock wall, encircling the top of the mountain.
