History

The 2000 Jasper Fire On August 24, 2000 a wildfire started near Jewel Cave. The fire burned 83,508 acres in the Black Hills and nearly 90% of Jewel Cave National Monument's land area.

Two brothers, Frank and Albert Michaud, filed a mining claim in 1900. This the first written record of Jewel Cave. The brothers intended to transform the cave into a tourist attraction. The remote location of the cave precluded it from being a commercial success. In 1908, US President Theodore Roosevelt set aside the cave as a National Monument following a local movement to preserve the cave.
