Jewel Cave National Monument is well-known for its spectacular and unusual cave and karst features. Since 1959, cavers have made a concerted effort to map Jewel Cave, and have discovered that it is among the longest cave systems in the world. Scientific studies indicate that the current exploration / cave survey represents only a fraction of what remains to be found.
