==The Cave==

[[File:Keelboat and flatboat.jpg|thumb|River pirates were some of the earliest settlers around Cave-in-Rock who preyed on the [[Ohio River]] [[flatboat]]s, [[keelboat]]s, and [[raft]]s, as profitable targets of goods, attacking the crews and pioneers who were easily overwhelmed and killed.]]

Cave-in-Rock's primary feature is a striking {{convert|55|ft|m|adj=mid|-wide}} riverside cave formed by wind and water erosion and by cataclysmic effects of the [[1811–12 New Madrid earthquakes]]. The cave is located at {{coord|37|28|07|N|88|09|21|W}}, just upriver (east) from the village. The first European to come across it was M. de Lery of France, who found it in 1739 and called it "''caverne dans Le Roc''". Other names for the cave include Rock-In-Cave, Rocking Cave, Rock-and-Cave, House of Nature, The Cave, Big Cave, and [[John Murrell (bandit)|Murrell]]'s Cave. The cave is the main feature of Illinois' [[Cave-in-Rock State Park]], established in 1929.<ref name=DNR>{{cite web |url=http://dnr.state.il.us/lands/Landmgt/PARKS/R5/CAVEROCK.HTM |title=Cave-In-Rock - State Park |publisher=Illinois Department of Natural Resources |url-status=dead |archiveurl=https://web.archive.org/web/20070402203142/http://dnr.state.il.us/Lands/Landmgt/PARKS/R5/CAVEROCK.HTM |archivedate=April 2, 2007 }}</ref>
