At over 40 miles, the Binkley Cave system is the longest cave in the state of Indiana and one of the longest caves in the United States. Exploration has been on-going for the past 40 years and has recently been noted to be a major drainage for Pleistocene era  glacial runoff. Among this finding, a discovery of bones were found in a large breakdown room deep within the Binkley System.
