This is a type named by Marion Heimlich for the Flint River in north-central Alabama, not the Georgia river of the same name.
We do not know anyone in Georgia that has used this type name.
Limestone-tempered vessels brushed or roughened horizontally with twigs about the body.
Vertical markings occur on the base and rim.
Incising occasionally occurs over the brushing and the exterior was sometimes stamped and the interior was roughened or brushed.
Middle Woodland to Early Mississippian.
