Magnetometer Map of Artifact Concentrations

Magnetometer map of artifact concentrations
Artifact distributions, overlaid on the magnetometer map, correlate to the structural remains. French artifacts, particularly the distinctive green-glazed earthenware sherds and quantities of nails and metal debris, were concentrated in the northern, higher area of the site, where archeologists found traces of La Salle's headquarters building, the chapel, and several smaller structures at Fort St. Louis. Spanish artifacts, including large quantities of blue and white Majolica ceramic sherds and other debris, were concentrated in areas somewhat overlapping the French settlement but also following the circular outline where traces of jacales structures were found. These artifact concentrations likely represent the trash dumped by soldiers and their familes while living in the circular room blocks at the Spanish presidio.
