Our tour guide and group. Most popular is the scenic tour I chose. The Park Service also offers a candlelight tour utilizing the historic entrance plus a wild cave tour. I learned my lesson in Iceland. No more cave tours with a low ceiling or where I have to crawl!
Jewel Cave is the third longest cave system in the world. It is 182 miles (292km) long. Jewel Cave was formed by gradual dissolution of limestone by acid-rich water.

Calcite crystals are formed by re-deposition of calcite by water saturated with the mineral.
Some of the platforms and stairs the Park Service put in to allow almost everyone to experience Jewel Cave.

Our Ranger testing the wind. The cave breathes to equalize the pressure. There was no movement of the ribbon today.
