Jewel Cave National Monument is in the Black Hills of South Dakota. The cave is the third longest known cave in the world, with over 208 mi (335 km) of mapped and surveyed passages as of 2020, and more being added each year. The cave was named after the large amounts of calcite (calcium carbonate) crystals found in the cave. The cave offers plenty of underground beauty, however, offers a variety of things to do on the surface.





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.



Jewel Cave National Monument is in a large pine forest.

Flora and fauna


There are many wildflowers in the National Monument. As with many national parks and monuments, there are non-native species that the managers actively work to remove. This work restores the area to its original condition and removes the threat non-native species often present to the native species.

Where there is a cave, there is often bats. Bats use caves to hibernate during the winter. Elk, mule deer, rabbits, squirrels, a variety of snakes, hawks, eagles, and other birds can be found in the area.



Spring: Rain or snow is common. Temperatures vary. Summer: Rain is common in June. Sunny and dry in July and August. Temperatures range from 70 to 95 degrees Fahrenheit. Fall: Mild temperatures and occasional rain or snow showers. Winter: Cold temperatures are common with occasional snow.

The cave itself is a constant, somewhat damp, 49 °F (9 °C).
