摘要：Lewis & Clark's pioneering "Voyage of Discovery" in 1804-06 crossed a significant karst terrane in Missouri, the only karst encountered on their journey to the Pacific Ocean. Geology and Speleology were yet to develop as sciences, yet Lewis & Clark made significant observations of karst, pseudokarst, and paleokarst features. The expedition's route took the explorers up-section from St. Charles to Kansas City, crossing notable karst in Ordovician and Mississippian carbonate rocks, into Pennsylvanian strata that is primarily clastic sediments with few karst features. The captains and/or other members of the Corps of Discovery passed the Florissant karst, visited pseudokarst Tavern Rock Cave, encountered caves in the Gasconade River drainage, noted a cave near Jefferson City at what is now Clark's Hill-Norton State Historic Site, and visited numerous springs. Upriver from Jefferson City, they noted paleokarst features known today as Bull Rock and Sugar Loaf Rock. They recorded in their journals the natural arch called Pierced Rock (Roche Percee'). The party likely saw Rocheport Cave, Wilton Cave, and the spring flowing from Lewis & Clark Cave in Boone County.

Lewis & Clark's pioneering "Voyage of Discovery" in 1804-06 crossed a significant karst terrane in Missouri, the only karst encountered on their journey to the Pacific Ocean. Geology and Speleology were yet to develop as sciences, yet Lewis & Clark made significant observations of karst, pseudokarst, and paleokarst features. The expedition's route took the explorers up-section from St. Charles to Kansas City, crossing notable karst in Ordovician and Mississippian carbonate rocks, into Pennsylvanian strata that is primarily clastic sediments with few karst features. The captains and/or other members of the Corps of Discovery passed the Florissant karst, visited pseudokarst Tavern Rock Cave, encountered caves in the Gasconade River drainage, noted a cave near Jefferson City at what is now Clark's Hill-Norton State Historic Site, and visited numerous springs. Upriver from Jefferson City, they noted paleokarst features known today as Bull Rock and Sugar Loaf Rock. They recorded in their journals the natural arch called Pierced Rock (Roche Percee'). The party likely saw Rocheport Cave, Wilton Cave, and the spring flowing from Lewis & Clark Cave in Boone County.
