Wisconsin is home to a major archaeological find: 14,500-year-old mammoth bones with human-made tool marks, suggesting that people have lived in the Western Hemisphere longer than experts had previously believed. Native American tribes formed over thousands of years after the mammoth hunters arrived. These groups included the Dakota Sioux, Winnebago, Menominee, Ojibwe, Potawatomi, Fox, and Sauk. Eleven Native American tribes still live in Wisconsin today.
