A good example of Oneota ceramics comes from the Kingston Oneota site in Iowa. This site is located in the SW1/4 of the NE1/4 of Section 36, T72N, R2W in Des Moines County on a bluff top overlooking the flood plain.
Oneota ceramics, specifically the variability found within them, have been a problem for archaeologists. This ceramic's traits generally include:
Oneota ceramic decoration is fairly simple. Lip notching occurs on 80% of all rims found; these impressions are made on both the interior and exterior of the vessel. Design motifs are restricted to the rim and shoulder - most are rectilinear, but a few have bulls-eye motifs. Groups of parallel lines separated by horizontal chevrons bordered by a single row of punctates, very characteristic of Blue Earth, is the dominant form at Kingston.
The one restorable jar at Kingston has a maximum diameter of 53cm at shoulder and 34 cm at mouth, with a height of 41cm. There were 55 handles found at the sight, some with unusual design elements. In all but one instance the handle was contiguous with the lip.
