These people didn’t become extinct. They first migrated northward to Mexico and founded Teotihuacan and then migrated to the Southeastern United States, where they became the elite of the Creek People’s ancestors. Ethnologist Charles de Rochefort wrote that the High King of the Apalache Kingdom in Northeast Georgia called himself Paracusa or Paracusa-te. This title was also used by the High King of the Satele on the coast of Georgia.
In the 1940s, the famous archaeologists, Robert Wauchope and Arthur Kelly, discovered an entire, very large, town, composed of these “coneheads” on the Etowah River, upstream from the big mounds, and northwest of Atlanta. Their fellow archaeologists dissed the discovery, claiming that the entire population of the town was afflicted with hydrocephalus (water on the brain)! The skeletons, unearthed by Kelly, have disappeared. The town site is now under the waters of Lake Allatoona.
