Cord roughened ceramic pot sherds recovered in 2016 when Two Rivers Archaelogy LLC completed an archaeological survey for a proposed bridge replacement located in Black Hawk County, Iowa. During this survey, the team discovered the partial remains of a single Late Woodland period (AD 650-1200) ceramic vessel. This vessel is an excellent example of cord-decorated pottery typed as Madison Cord/Fabric Impressed, which is a hallmark of the Keyes Phase of the Effigy Mound Tradition in northeast Iowa. A sample of carbonized food residue collected from the interior surface of the ceramic vessel yielded a convental radiocarbon age estimate of 1430 (+- 30 years) before the present. The rim of the vessel was assembled before it was donated to the UNI Museum.
