The Bingham brothers, Jesse and Tom, discovered it in 1881 when they heard a loud whistling sound coming from the natural opening of the cave (“Wind Cave National Park”). Currently, 143.16 miles of passages are mapped out. It is the “3rd longest cave in America and the 7th longest cave in the world” (“Cave / Karst Systems"). Strong winds go in and out of the cave due to changes in the barometric pressure inside and outside of the cave, hence how it got its name (”A Brief History of Wind Cave National Park”). Portions of the cave are close to 300 million years old making it one of the oldest caves in the U.S. Formed in the Madison Limestone formation, this grandiose cave is consistently 53 degrees and “relatively dry so it contains few stalactites and stalagmites” (“Wind Cave National Park”). However, the cave does house an abundant amount of rare calcite formations resembling irregular honeycomb known as boxwork. The boxwork projects from cave ceilings and walls and has a rusty color created in wafer-thin sheets (“Cave / Karst Systems"). In other areas, cave popcorn, flowstone, and frostwork are visible. Even though much of the cave has been discovered, exploration is
