Illinois River Encounter

Learn the story of the Illinois River in this unique gallery. As you enter, you'll see a 400-gallon aquarium containing native fish species from the Illinois River. In the main exhibit, along one side, learn about the natural history of the river from the time of the Kankakee Torrent more than 14,000 years ago until the present.
