New Discoveries at Jewel Cave

Jewel Cave GrowingThe map of the Jewel Cave National Monument continues to expand in South Dakota. Currently the Jewel Cave holds the claim of the third largest known cave in the world, but it has not always been easy. Back in July of 2011 tours of the mine had to be put on hold when the 28 story elevators for sightseers had a serious mechanical problem. Once the elevators were back on track, the visitors were once again able to enjoy the Monument Center and volunteers were recruited to continue the search for more areas of the cave system. The Cave is now open again with even more to explore and discover.

Looking to explore the rocks of North America this summer, consider a trip to South Dakota to this rare and special cave.
