This is a Mississippian ware associated with the Mounds of the Wateree River. Surfaces are mostly plain or burnished, with filfot cross and line block complicated stamping also present. Adamson is tempered with medium sand to medium grit. DePratter and Judge (1986) thought the Adamson Phase dated from 1250 to 1300 AD, based on seriation. Subsequent work by Cable et al (1998) suggests a later date.
