Today was a cave tour of the caves that Mark Twain (Samuel Clemens) explored as a child. These are dry caves, there are no stalagmites or stalactites.
Mark Twain Cave and Cameron Cave instead have a multitude of narrow, winding passages.The caves are made mostly of a soft limestone called Louisiana Lithographic Limestone and found only in a 35-mile (56 km) area around Hannibal and Louisiana, Missouri. The limestone has been estimated by geologists as around 350 million years old, while the cave passages were formed some 100 million years ago. Mark Twain Cave covers some 6 1⁄2 miles (10.5 km) consisting of four entrances and 260 passages, maintaining a year around temperature of 52 °F (11 °C).

Personally, we found it to be too political, but perhaps that was how Mark Twain was.........
