Behind the scenes of Journey Indiana: Underground, WTIU's most recent documentary. This one-hour program takes viewers inside some of Indiana's most fascinating yet little-known places!

Underground the Big Wyandotte cave in southern Indiana. Tour groups are gathered, wearing hard hats with head lamps. The cave room is just tall enough to stand in—around 6-8 feet high.

Inside of a cave in Corydon, IN. Pre-historic bones are uncovered in a shallow, square dig site, roughly 1 by 2 feet in size. Dig tools are neatly arranged in a row above the square cut out. The bones are very small, mostly animal teeth.

A 7-person caving group congregates outside the entrance to a river cave during Cave Capers, an annual gathering in Southern Indiana hosted by the Central Indiana Grotto. Their gear includes waist and chest-high waders, some bright red, some purple; hard hats; boots and head lamps. A short waterfall flows out of the cave entrance, surrounded by lush green plant life.

A Spring Mill tour guide stands tall in a rectangular boat, pointing to rock inside of Twin Caves. A small group of 4-5 people watch and listen intently. All are wearing bright orange life vests. The entrance to the cave is covered in moss and fern plants.

While we might be better known for corn fields and race tracks, did you know that just beneath the surface, Indiana hosts over 4000 incredible, pre-historic caves? We are home to underground waterfalls, bones from the ice age, and one of the longest cave systems in the U.S.!
