Circular earth lodges were built to serve as places to conduct meetings and important ceremonies. Remains of one of the earth lodges were carbon dated to 1050 CE. This evidence was the basis for the reconstructed lodge which archeologists later built at the park center. The interior features a raised-earth platform, shaped like an eagle with a forked-eye motif. Molded seats on the platform were built for the leaders. The eagle was a symbol of the Southeastern Ceremonial Complex, which the people shared with other Mississippian cultures.
