Defined at the Irene site, 9Ch1, in Chatham County. Named for the Savannah River and the city of Savannah by Joseph Caldwell and Antonio Waring.
Complicated stamping on grit-tempered pottery with unfolded rims. Applications of the stamped designs are deliberate and clear. Overstamping often occurs, however. Known designs include figure eight, concentric circles, a single terminal element of the figure eight, concentric circles with a cross in the center, and a simple figure eight with a cross in the center of each terminal circle. Vessel forms are globular or cylindrical with well-defined shoulders. Vessels are usually large with diameters sometimes exceeding 30 centimeters. Rims are straight to flaring, sometimes everted. Lips are squared, rounded or stamped-beveled.
