The Park Service sunk a 300 feet (91 m) elevator shaft to a previously remote cave area, and built concrete walks and metal stairs and platforms along a one-half-mile loop. The "Scenic Tour" was opened in 1972. Most modern-day visitors tour that part of the cave. In August 2000, an 83,000 acres (340 km)

The discovered areas in the cave account for only about 3–5% of the estimated total air volume of the cave, which is believed to be roughly 8 billion cubic feet (230 million cubic meters). This puts estimates for the total length somewhere between roughly 4,400 miles (7,100 km) and 7,300 miles

Frank and Albert
Michaud, two local prospectors, discovered the cave in 1900, when they felt cold air blowing out of a small hole in a canyon. It is unknown whether any previous inhabitants of the area were aware of the natural cave opening, which was not large enough for a person to enter.
