Named after the Irene site, 9Ch1, in the northern portion of Savannah excavated in the late 1930s. This obvious name was never defined as such in the 1930s, but Chester DePratter formally defined in years later. Related to Lamar Complicated Stamped.
Complicated stamping on grit-tempered pottery. The stamping is distributed over the entire exterior of the vessel. In the Irene assemblages, the filfot cross is the most common motif. The stamping is executed carefully in this phase with little over-stamping. In the later phases of Pine Harbor and Altamaha, designs include concentric circles, figure nines, crosses, and line blocks. In these later phases stamping is less well executed. Most of the complicated stamped vessels have decorations just below the lip. These rim decorations include reed punctuations, appliquщ strips, rosettes, lugs, and nodes. Known vessel forms include an elongated globular body with a slight shoulders and wide-mouth hemispherical bowls. Rims are flaring, straight, or incurving. Lips are rounded or square. Bases are round.
