Deep Darkness Exploration

Do you have what it takes to go across the
Ohio-Indiana stateline to explore deep darkness?

Would be adventurers can now descend, climb, crawl and kayak deep underground in Indiana’s longest cave system.  Indiana Caverns, near Corydon Indiana recently opened a new, guided high adventure cave exploring trip.

Descending a 93 foot shaft into a remote section of passage discovered in 2010, explorers then descend a steep mountain of breakdown using a hand line before reaching the underground river, 200 feet underground.  Splashing and wading downstream, eventually the party of no more than 10 has to take to kayaks to continue exploring the deepening water.  The underground stream features a large population of blind cave fish as well as blind cave crayfish and other spelean species.

The section of cave that is visited is just a tiny portion of the vast Binkley Cave system south of Corydon Indiana.  The first serious exploration and mapping was done by the Bloomington Indiana Grotto of the National Speleological Society.  Since 1967, all research and exploration has been done by the Indiana Spelological Survey, with exploration quickening since 2009.  The length of the system has grown for 22 miles in 2009 to 42.5 miles and growing, making it the 7th longest cave in the United States.
