The Toltec Mounds site (3LN42) (A.D. 700-1050) in central Arkansas has intrigued archaeologists for decades. Although it dates well within the Woodland Period and has many features characteristic of a Woodland Period site, including grog-tempered pottery and a reliance on hunting and gathering, its mound-and-plaza layout is an architectural design suggestive of the later Mississippi Period (A.D. 1000-1500). This confusion is addressed in this thesis by examining two ceramic assemblages from different building stages of Mound D, the last mound to be altered at the site. The ceramics show an affiliation with northeastern Arkansas that has been underemphasized in the past, and that may provide more information on Toltec's relationships with its neighbors through the end of the Woodland Period.
