The Indiana Caverns are tucked away near Corydon, Indiana, and are a part of the Binkley Cave system. It was originally explored around the 1930s, and today, you can explore the cave as well.
It is what's known as a solutional cave, which means it was formed as limestone was dissolved by underground streams with a high concentration of carbonic acid within them.

When a sinkhole opened up above it at some point in the early 1900s, it was game on. The exploration began, and new discoveries are still being made all the time.
In 2010, a portion of the cave now known as Blowing Hole Boulevard was discovered to have an 85-foot-high room at its west end. Discovered in this room were many sets of bones dating all the way back to the Pleistocene Ice Age.

In 2013, the caverns opened to the public, and they have an adventure-packed day planned for you.

Zip over the park on their thrilling single-rail zip coaster, experience a (controlled!) 50-foot drop straight down, or find your way out of an escape room. The adventure is non-stop.
For the bravest of spelunkers, the adventure park also offers what's called the "Deep Darkness" tour - an intense four-hour caving adventure in which you will wade through water, crawl through small spaces, and really dive deep into the more than 44-mile cave system.

Most commonly spotted fossils include coral and brachiopods, though sometimes someone spots something that nobody has before.

If it wasn't for a sinkhole that opened in the early 1900s, this underground fortress may have gone unnoticed forever.
