The Lake Okeechobee region contained some of the most sophisticated indigenous cultures that ever existed north of Mexico. Its towns built large earthworks and ponds in the shape of the ceremonial scepters carried by leaders in the Southeastern Ceremonial Mound Culture, but they were built several centuries before the Southeastern Ceremonial Mound Culture appeared elsewhere. Its engineers constructed several hundred miles of canals and raised causeways to interconnect the towns. They even built locks to enable cargo canoes to bypass rapids. Yet despite all this cultural precociousness, so far there is no evidence that the people of South Florida ever practiced large scale agriculture. However, intensive cultivation of raised garden beds in a semi-tropical climate, also a practice of the Mayas, may have produced a far higher percentage of their diet than anthropologists currently presume.
The presence of crescent shaped temple mounds in the Florida Peninsula strongly suggests cultural contacts with Maya ethnic groups, who worshiped the goddess, Ixchel. Very few Florida archaeologists have been willing to suggest publicly that Florida, Mesoamerica and South America had direct cultural contacts. Those who did, were all ostracized by their peers. However, the linguistic and architectural evidence is overwhelming for contacts between illiterate Maya merchants and the indigenous peoples in Georgia – which is north of Florida.
