Bluffs composed of 425-million-year-old St. Peter sandstone, canyons formed by water erosion, and the streaming Cascade Falls are among the park's striking features. Home to more than 200 species of birds and myriad woodland flowers, the 1,600-acre park is south of
Utica in north central Illinois and a stone's throw away from
Starved Rock State Park on the
Illinois River.
