The oldest Native American civilization in the state of Georgia can be found along the Atlantic coast on Sapelo Island. Known as the Sapelo Island Shell Ring Complex, this site consists of three doughnut-shaped Indian mounds built from successive layers of different types of shells including oysters, conch, clams, and mussels. The rings rise approximately 20 feet above the tidal marsh and the largest of the three has a diameter of 255 feet. The site has been radiocarbon dated at 2170 B.C. making it older than many of Egypt’s pyramids! (Similar sites have been discovered in Florida such as the Horr’s Island Mounds and Guana River Shell Rings which are even older.)

There are two theories regarding the formation of the Sapelo Shell Rings. One theory holds that they were built purposefully, in a short burst of building activity, as intentional monuments and ceremonial centers. The other theory holds that they were unintentional monuments built up over many years as NativeAmericans discarded their trash. This theory holds that the circular shape of the shell rings was the result of Native Americans living in circular villages and discarding their trash behind their homes which resulted in a circular trash ring that gradually built up over time. (A third hybrid possibility, gradual but intentional, will be discussed later wherein the residents purposefully discarded their trash behind their homes knowing that it would slowly accumulate into a protective, surrounding wall.)
The latest research seems to support the gradual accumulation theory. The Sapelo Shell Rings are filled with not only various types of shells but also the bones of fish such as catfish and mullet, mammals such as deer and raccoon, and reptiles such as alligator. In other words, the shell rings are built from the refuse of daily living and preliminary research shows that this refuse accumulated over a long period of time as opposed to being deposited in a single building event as one would expect if the rings were intentional monuments.

Archaeologist Victor Thompson researched and excavated this site over several years. His research showed that one of the shell rings first began as several pits spaced equally apart filled with shell and other refuse. Over time these trash pits turned into shell heaps and later the areas between these shell heaps were also utilized for dumping shells and other refuse. Thus the circular form of the ring took shape as the residents, over a long period of time, continued dumping their refuse between and on top of the original shell heaps. This process resulted in a less than perfect circle and also gave the ring a decidedly “lumpy” appearance. If this had been built as an intentional monument one would expect the circle to be more symmetrical and the height to be more uniform but they’re not which is exactly what you would expect to see if the rings accumulated over a long period of time.
Party Time at Sapelo
What does seem to be intentional is the central plaza within the shell rings. (View QTVR) Thus, even though the shell rings themselves may be trash piles, their central plazas were indeed purposefully constructed as a location for ceremonies, feasts, dances, games and other activities of village life. In fact, Thompson noted that the interior of the shell ring was lower than the ground level outside the shell ring. He proposed this could have resulted from the villagers repeatedly cleaning the central plaza area by sweeping and dumping this refuse onto the shell ring. This would have added to the height of the ring while simultaneously lowering the ground level within the ring.
What’s For Dinner?
By analyzing the bones and shells discarded in the shell ring, Thompson was able to discover not only what the people living at Sapelo ate but also when they ate it. The evidence showed that the villagers ate oysters primarily during the winter months. They ate clams throughout the year but more so in the warmer months. As to be expected, they also ate a lot of fish with two varieties of sea catfish being preferred based on the quantity of remains found. Fish in the drum family were the second most eaten fish including such varieties as kingfish, silver perch, sea trout, Atlantic croaker and star drum. Interestingly, only one variety of freshwater fish was eaten: the sunfish. The remains of crabs, primarily blue crabs but also Florida stone crabs, were the second most abundant food source discovered in the shell trash heaps.
These villagers also ate white-tailed deer, opossum, raccoon, turkey, bottle-nosed dolphin, gray squirrel, Atlantic sea turtle and fresh water turtles, little green heron and domesticated dog. Minus the dolphins, dogs, turtles and herons much of the diet of these villagers 4,000 years ago is remarkably similar to those living in the area today. (Continues….)
