The Hayti Bypass Site (23PM752) 

The Hayti Bypass Site was identified during the preliminary design to relocate and widen US Route 412 in Pemiscot County, Missouri.  The site was excavated by the Center for Archaeological Research (CAR) at Missouri State University under contract with the Missouri Department of Transportation after it was determined the site could not be avoided. 

Hayti Site Plan

Initial testing indicated that the site could provide important information about subsistence and material culture of prehistoric people in the Mississippi River Valley of Pemiscot County.  With their research questions in mind, CAR archaeologists excavated the entire portion of the area to be impacted by the new relocated Route 412.  Based upon material recovered from over 200 prehistoric features archaeologists concluded that the site was primarily occupied during the Middle Woodland (A.D. 0-380), the Late Woodland (A.D. 400-600), and Early Mississippian (A.D. 1000-1100) time-periods.  These features provided some of the best available data on Woodland and Early Mississippian occupations in the Mississippi River Valley of the Missouri Bootheel.  Specifically, evidence of the Varney tradition of the Mississippian time-period (A.D. 1050) was discovered at the Hayti Bypass Site.

The Hayti Bypass Site produced important new data regarding plant usage during the Woodland and Mississippian occupations in the Mississippi River Valley of Pemiscot County, Missouri.  The archaeological investigations produced important information about the region’s prehistory, as well as Missouri’s prehistory.  A technical report was produced by CAR on the results of their investigation, Woodland and Mississippian Occupations at the Hayti Bypass Site, Pemiscot County, Missouri (1995).
