🏆 Kaskaskia Bottomlands — Recreation area in the Kaskaskia River bottomlands — near Illinois’s first state capital and the only part of Illinois west of the Mississippi
Randolph County State Recreation Area provides outdoor recreation in the Kaskaskia River bottomlands near Chester — home of E.C. Segar, creator of Popeye the Sailor Man! Chester’s riverfront features a Popeye statue and museum. More significantly, the nearby town of Kaskaskia was Illinois’s first state capital (1818–1820) until the capital moved to Vandalia. In 1881, a catastrophic Mississippi River flood destroyed old Kaskaskia and shifted the river channel, stranding the townsite on the Missouri side — making it the only part of Illinois west of the Mississippi.

Frequently Asked Questions
What are the American Bottoms?
The American Bottom is the wide Mississippi River floodplain in southwestern Illinois — some of the richest agricultural land in the US. This fertility supported Cahokia (the largest pre-Columbian city in North America) and later attracted French, British, and American settlers. The bottomland remains highly productive farmland today.
Wildlife & Nature
Randolph County State Recreation Area provides outdoor access in the Mississippi River bluffs of southwestern Illinois — a region steeped in French colonial history. Kaskaskia — the first state capital of Illinois (1818-1820) — lies nearby, now a ghost town repeatedly flooded by the Mississippi. The bluffs and bottomlands support diverse wildlife. Turkey vultures — with 6-foot wingspans — ride thermal updrafts along the limestone bluffs. Cooper’s hawks hunt in the forest. White-tailed deer are the primary game species. The Mississippi River bottomlands provide critical habitat for migrating waterfowl. Channel catfish and flathead catfish inhabit the river. Box turtles are common in the upland forests.
