Frank and Albert Michaud discovered Jewel Cave in 1900, and it became a National Monument in 1908.
The only known natural entrance is located 14 miles west of Custer, South Dakota on US Highway 16 at an
elevation of 5322 feet above mean sea level. The cave is located entirely in the Pahasapa Limestone.
The Civillian Conservation Corps conducted the first survey of Jewel Cave in 1936.
Subsequent survey was conducted from 1959 to present by volunteers from around the world.
This map shows the entire cave complex at it’s last digital updated mileage of 219.66 Miles (353.51 Kilometers) as of February 2024. The Jewel Cave National Monument Map Poster is 24″ wide x 18″ tall.
