This is a small group of rectangular designs of Swift Creek Complicated Stamped described by Gordon Willey on the northwestern Florida Gulf Coast. Named after St. Andrews Bay in northwestern Florida. The rims of the vessels define this as early in the Swift Creek period.
Rectilinear complicated stamping on sand and mica-tempered pottery. Designs include line block, hatched rectangles, diagonally bisected rectangles with each triangular half filled with hachure, and concentric rectangles or triangles. Rims are incurving, notched, and scalloped. Lips are flat-round or flat.
