A new cave is set to open to the public in Harrison County near Corydon, Ind.
The cavern is the 11th largest cave in the U.S.
It’s a nearly 40-mile long underground trail, rich in history and prehistoric bones.
Crews have been working on opening up a passageway so the public can see the discovery. It’s a task that hasn’t been easy.
“It’s an expensive proposition. In this cave, everything had to be carried in by hand. Tons and tons of steel, concrete. We had to blast a tunnel,” said Gary Roberson with Indiana Caverns.
The cave has waterfalls, lots of formations and there’s even a boat ride! It’s expected to open to the public in May.
