Description

All of the features at the site are badly eroded, sustaining damage over the years from natural forces, pot hunters, and joy riders on ATVs. The site currently consists of three platform mounds and a raised shell midden ringing a rectangular central plaza area. A fourth mound at the southern edge of the site may have existed; but over time has been eroded away into the adjacent Bayou Teche. The plaza area, delineated by the mounds and shell midden, covers approximately . Located at the western corner of the plaza is Mound A, the largest of the existing mounds. It is approximately in height and in diameter. Mound B, at in height, is located to the northeast. to the southeast of Mound B is Mound C, a low rectangular platform in height, although it may have once been much taller. An elevated area that extends from the base of Mound A along the southwestern edge of the plaza toward the southeast is a shell midden consisting of high concentrations of '' Rangia cuneata'' shell, grog-tempered Plaquemine culture pottery sherds and other artifacts. Its terminus at the southern point of the plaza may have been the location of a fourth mound possibly described in early accounts of the site. The combined area of the mounds and plaza covers , although village habitation areas are thought to have existed outside this main precinct.
