Old Indian Boundary Line Prairie

Come visit Old Indian Boundary Line Prairie in Princeton, IL

Established in 1816, Illinois’ Old Indian Boundary Line ran from the southern tip of Lake Michigan down to the Rock River’s confluence with the Mississippi River. In 1982, a decision was made to restore a 7-acre parcel of land along SR 26 back to native tallgrass prairie habitat. Today, the site has matured beautifully and is dominated by a lush, healthy stand of big bluestem grass with an accompanying mix of mountain mint, coneflowers, sunflowers, asters and other prairie wildflowers.
