“Get muddy with a buddy! This adventure begins with the Red Room ladder entrance into Marengo Cave’s New Discovery. Hidden from visitors for more than one hundred years, this section of cave was discovered on June 6th, 1992.
Trudge through the “Valley of Lost Soles”. Visit Stewart Spring, Indiana’s 13th largest producing spring, from underground.
Then exit from the “Pig Pen” named for the slimy wet clay that you’ll be covered in. Great, not so clean fun!”
