Description

Indiana Cavern is a show cave in Southern Indiana, which is a part of the Binkley Cave System. This system is almost 60 km long and the longest cave of Indiana and the 11th longest of the U.S.A. [2013]. The one-hour walking tour includes a 10 m high underground waterfall and is followed by a 20-minute boat ride. The so-called Bone Mountain is the largest deposit of Ice Age animal bones in North America. Because of the boat ride it is important to wear comfortable walking shoes which allow safe boarding. Strollers are not allowed.

This show cave was developed by Gary Roberson. He developed two other caves before, so he is definitely a professional in this field. He is also a well known caver and explored the Binkley Cave System since 1967 when he was 11 years old. His book 50 Years Under the Sinkhole Plain is a description of his life exploring this cave system. It is available as pdf download from the author.

The entrance with the ticket office also has interpretive displays and a media room. It is completed by a walking trail showing karst features and visible signs of the cave below. Typical for US show caves are the picnic area and the gemstone and fossil mining.
