Indiana’s Show Caves

Nov 17, 2020

One of Indiana’s most prominent exports is its limestone. And where there’s limestone, there are caves. Indiana has over 3,000 known caves, and more are found every year.

Today we talk about Indiana's show caves with guests from Bluespring Caverns, Marengo Caves, Squire Boone Cave, and Indiana Caverns, as well as experts on cave geology and exploration. We find out why Indiana has so many caves, and what it takes to explore them.
