Cave-in-Rock State Park : ウィキペディア英語版 | Cave-in-Rock State Park }} Cave-In-Rock State Park is an Illinois state park on in Hardin County, Illinois in the United States. The state park contains the historic Cave-in-Rock, a landmark of the Ohio River. It is maintained by the Illinois Department of Natural Resources (IDNR).〔Joe McFarland, "The Hole in the River", ''Outdoor Illinois'' XVIII:11 (November 2010), pages 2-5.〕 ==Geology==
The Cave-in-Rock was worn into the limestone bluffs of the Ohio by river floods, especially during the meltoff following the Wisconsin ice age. It is not a karstland cavern like Mammoth Cave in nearby Kentucky; it is an obvious, tunnel leading a long distance into the bluff.〔
