The Jewel Cave National Monument is the home to the Jewel Cave. The area?s special for being the second longest cave in the world, measuring 151.34 miles of total mapped passageways. However, new explorations show additional passages. It is also considered as one of the best caves to be ever included in the National Parks system.

The Jewel Cave National Monument got its name after the appearance of its interiors. The caves, instead of just having the regular, wondrously shaped rock formations have something else to offer: the sparkling calcite crystals alongside other formations.

Discovered in the year 1900 by local homesteaders, the Jewel Cave National Monument is one of the best preserved and unspoiled areas of the sort. It is continuously being taken care of by the National Parks system with the help of new helpful technologies.
