Refining Woodland Period Chronology and Interactions in Northeastern Missouri: Contributions from the Avenue of the Saints Project

The recently completed Avenue of Saints (AOS) highway project in the Mississippi Valley of northeastern Missouri resulted in the documentation of Woodland period sites ranging from approximately 200 cal BC to AD 1200. This article updates the existing Woodland chronology for this locality based on new information collected during the project. Data pertaining to Early, Middle, and Late Woodland sites are presented. The approximately 1,400-year occupation span provided researchers an opportunity to view diachronic trends in tool manufacture, subsistence economy, and landscape use. Based on regional comparisons of ceramic and lithic technologies and vessel decoration, the Woodland sequence in northeastern Missouri was influenced by population movements originating from east of the Mississippi River and from southern sources in the Salt River valley.
