The Dumaw Creek Site near Pentwater, Michigan, preserves a seventeenth-century village and cemetery from the terminal Late Woodland period, making it one of Michigan’s youngest prehistoric sites just before European contact. Occupied around 1605 to 1620, it was likely home to people ancestral to the modern Potawatomi, who lived in semi-permanent wigwams and supported themselves by hunting, fishing, and raising corn and pumpkins. Burials and artifacts reveal both daily life and mortuary customs, including copper ornaments, pottery, tools, and shell objects that connect the community to broader Great Lakes traditions. Later archaeological work established the site’s significance despite early loss of provenience.
