Tensas,
Ouachita, and
Little Rivers. It had nine
platform mounds and a perimeter embankment that were built before 700 CE. A historian, John W. Monette, in 1844 described the complex as occupying close to 400 acres and noted the existence of twelve small mounds and one large one. The embankment was started during the Middle
Baytown period, with periodic repair work taking place during the Late Baytown period. The largest mound, Mound 5 ( also known as the "Great Mound" ), was in height. and had three levels, the bottom two rectangular and the third on the top a truncated conical mound. Monette described the lower level of Mound 5 as being by at its base and rising to the height of . He described the conical mound at the top as . In 1883 the site was visited by the prominent ethnologist
Cyrus Thomas, who described the group as then consisting of six mounds within an embankment, with some of the smaller mounds having been largely destroyed. One had been turned into a modern cemetery, which can still be seen today on the grounds of the local Methodist Church. The Great Mound had also been reduced, by this time it was only in height, in length and in width. In 1931 the mound was drastically reduced in size, the majority of its remaining mass being used as fill for a nearby bridge approach. Today the mound is only in height. ==Excavations==
