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.
