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. Over 166 miles of interconnected passages have been discovered so far, and studies indicate that this represents only a fraction of what remains to be found.
