Man Mound

Man Mound in Greenfield, Wisconsin, is a precontact Late Woodland earthwork and the only surviving anthropomorphic effigy mound in North America. Built between about 750 and 1200 A.D., it takes the form of a human figure with its head to the south and feet originally extending westward, with two horns or a horned headdress that suggest ceremonial or religious meaning. It may have been used as a burial site, though it has not been excavated. First surveyed in 1859, it was later partly damaged, then preserved through local acquisition, park protection, and national historic designations, making it a rare surviving link to Late Woodland culture.
