Dogtooth Bend Mounds and Village Site is an archaeological site located on the western shore of Lake Milligan in Alexander County, Illinois. The site includes two mounds and a village site stretching northwest of the mounds. The village was inhabited by Middle Mississippian peoples from roughly 900-1600 A.D. It likely served as a trade hub and a social center for residents of the surrounding farmland. Formal archaeological investigation of the site was initiated in 1950 by Irvin Peithman of Southern Illinois University.[2]
