When was Jewel Cave first discovered?: The year was 1900. Prospectors Frank and Albert Michaud found a small opening in the cave and filed a mining claim on the land. Once they opened it up, they discovered many different and colorful rock formations in the gigantic caverns and named their discovery "Jewel Cave".

Just how big is Jewel Cave anyway?: According to the National Park Service, the cave has more than 200 miles of mapped and surveyed passages. Just two years ago a team of six volunteers mapped the 200th mile of the cave and commemorated the event.
