Description

Frank and Albert Michaud, and Charles Bush discovered this cave by hearing wind rushing through a hole. 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.

For a long time not much happened with the cave, but the then known part was destroyed by people taking away the calcite crystals. Fortunately the cave was protected by Presidential Proclamation in 1908, when it became a National Monument. This protected especially the beautiful and extraordinary new discoveries since the 1950s.

Jewel Cave is the third longest cave of the world. Most of this cave system was discovered and surveyed by Herb and Jan Conn, who described the story of this exploration in their book The Jewel Cave Adventure; Fifty Miles of Discovery Under South Dakota. Huge sections are connected by very narrow and difficult intersections.

Jewel Cave is famous for extraordinary speleothems. Most impressive are the so-called dogtooth spars, which are huge calcite crystals covering the walls. Chambers and clefts covered whith such crystalls all over make the visitor feel like walking inside an extra large geode. Additionally many other rare speleothems were found in Jewel Cave, like boxwork, frostwork, and hydromagnesite balloons.

Todays visitors enter a part new discovered during the mid 20th century, not the one which was discovered originally. This part of the cave is entered by an elevator directly from the visitors center. The development of the paths was done very carefully to minimize the impact on the cave.

The historic entrance is still used for the so-called Candlelight Tour. This tour is a bit strenuous and held only during the summer. The path is not paved, there are wooden stairs and narrow passages.
