Named after Wilmington Island on the northern Georgia Coast by Joseph Caldwell.
Curvilinear, complicated stamping on clay or grog-tempered pottery. Common design elements include concentric circles and figure-eights, although others may occur. Known vessel shapes are cylindrical jars and hemispherical bowls. Rims are straight, occasionally slightly flaring. Lips are rounded or carelessly squared. Bases are round to slightly conoidal. Walls of the vessels are thick, and the interiors of the vessels are poorly finished, showing brushing and scraping impressions. Large lumps of partially-extruded temper often can be seen o n the interior of the sherds.
