The exploration of Jewel Cave began about 1900 when two South Dakota prospectors, Frank and Albert Michaud, and a friend, Charles Bush, happened to hear wind rushing through a hole in the rocks in Hell Canyon. Enlarging the hole, they found a cave full of sparkling crystals. They filed a mining claim on the "Jewel Lode," but they found no valuable minerals, so they tried turning the cave into a tourist attraction instead. The business was never a success, but the cave did attract attention, and in 1908 Jewel Cave National Monument was established to protect the small but extraordinarily beautiful cave. Fifty years later exploration of the cave intensified. Led by the husband-and-wife team of Herb and Jan Conn, modern-day cavers have discovered new wonders and explored many additional miles of passages. Today the cave is among the world's longest and is renowned for its variety of formations.

Cave Exploration
When Herb and Jan Conn were first persuaded to join a caving expedition in Jewel Cave in 1959, the couple responded without enthusiasm. Their passion was rock climbing, not crawling around in dark, gloomy holes. Little did they know they would spend much of the next 21 years in Jewel Cave, lured by the thrill of discovering the secrets of yet another mile of never before seen cave. The caving parties led by this husband-and-wife team would make 708 trips into the cave and log 6,000 hours exploring and mapping. "Our exploration of Jewel Cave, which started out as a mild diversion, quickly mushroomed into an all-absorbing interest," the Conns explain in their book, The Jewel Cave Adventure. On a typical day, the Conns and their fellow cavers spent 12 to 14 hours underground. Outfitted in hard hats, carbide lamps, gloves, loose fatigues, elbow and knee pads, and boots, the explorers squeezed, crawled, and climbed their way through Jewel Cave's complicated maze. The going was rough. During rest stops they often munched on mangled sandwiches and squashed fruit while massaging sore muscles. Names they gave to some passages, such as Contortionist's Delight and The Miseries, tell the story.

As years passed and more miles of cave were found, it became apparent that Jewel Cave was one of the world's most extensive caves, full of scenic and scientific wonders. The explorers found chambers with exquisite calcite crystals and rare cave formations. One much-decorated room discovered by the Conns - the Formation Room - is a highlight of the Scenic Tour today. They also found rooms as large as 150 by 200 feet, passageways as long as 3,200 feet, and a place where the cave wind blows at speeds of up to 32 miles per hour. The cave, they discovered, is truly a rare and precious jewel.

In 1980, after discovering more than 65 miles of cave, the Conns retired. A new generation of cavers has already pushed the known boundaries of the cave to more than 100 miles. But the mystery remains. As the Conns have said, "We are still just standing on the threshold."

Surface Activities & Information
You may take some time on your visit to Jewel Cave National Monument to experience the world above the cave. In the 2 square miles that make up the park you can have a picnic, take a nature hike and enjoy some of the plants and animals of the rugged hill country of the Black Hills. In the ponderosa pine forest which covers the park you may see mule deer, white tailed deer, elk, coyotes, porcupines, squirrels, marmots, several species of chipmunks, and several species of birds including the golden eagles and hawks. Plants of both the prairie and mountains grow here, and in spring and summer wildflowers color the landscape.

The visitor center has information on all aspects of Jewel Cave National Monument. Various books and brochures are available, and park rangers are on duty to assist you with planning your visit and answering your questions. Up-to-date cave information is also available.
