Interpreting the South Flats Earthwork (20MU2): Insights Gained from Geophysical Surveys

ABSTRACT Michigan's prehistoric earthen enclosures are among the least understood archaeological sites in the state. This paper explores the function of the South Flats Earthwork (20MU2) using remote sensing strategies to reveal aspects of its internal structure not available through excavation. Ground penetrating radar and magnetometry were employed to explore this fragile archaeological site. Results, coupled with excavation data, suggest that South Flats was the work of a small-scale society and a locus of storage and food exchange through kin ties.
