When was wind cave formed?
January 9, 1903
Wind Cave National Park/Established
How long did it take for the Wind Cave to form?
between 40 and 60 million years ago
Time, Time, Time Seas continued to advance and retreat over the area for the next 240 million years. Sediment alternately deposited and eroded from atop the cave. The cave probably developed slowly until the most recent Black Hills uplift between 40 and 60 million years ago.
What is the history of Wind Cave?
On January 9, 1903, President Theodore Roosevelt signed the bill creating Wind Cave National Park. It was the eighth national park created and the first one created to protect a cave. The parklands at that time were small and there were no bison, elk, or pronghorn. They came later as the park boundaries expanded.
How did these caves form?
Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
What is the Wind Cave made out of?
limestone
Wind Cave is one of the largest caverns in the world, a labyrinth of passages carved out of limestone beds that have existed for 60 million years.
How much of Wind Cave has been discovered?
Approximately 95 percent of the world’s discovered boxwork formations are found in Wind Cave. The cave is recognized as the densest cave system in the world, with the greatest passage volume per cubic mile….

Who founded Wind Cave?
Long considered sacred by Native Americans, the cave was discovered by outsiders in 1881 when brothers Jesse and Tom Bingham were drawn to a small hole in the ground by a loud whistling noise and the accompanying wind.
Who discovered Wind Cave?
How do crystals form in caves?
All crystals form as a result of two processes, called “nucleation” and “crystal growth,” in a “supersaturated” liquid solution (a liquid with something dissolved in it; for example, salt). This will occur in a cave if it is flooded with one of these liquid solutions for as long as a hundred thousand years or more.
Why Is Wind Cave called Wind Cave?
The name Wind Cave comes from the wind that naturally blows out (and in) of the small natural entrance to the cave. Wind Cave is most known for its delicate calcite formations called “boxwork”. The vast majority of the world’s discovered boxwork, 95%, is found in Wind Cave.
How deep is the Wind Cave?
Wind Cave by the Numbers
| 4 | new miles of cave discovered every year. |
| 7th | U.S. national park, designated by Theodore Roosevelt in 1903. |
| 654 feet | maximum depth of the cave from its entrance. |
| 300 | stairs you’ll climb or descent on the cave’s natural entrance tour. |
| 75 mph | maximum recorded wind speed at the cave’s entrances. |
How did the Wind Cave get its shape?
The uplift opened more fractures in the limestone, allowing more cave to form. Water did not flow through the cave like a river. Instead, the water probably sat in the limestone for long periods of time, slowly enlarging small cracks into larger passageways, creating Wind Cave’s complex maze-like pattern.
How does water dissolve rock in Wind Cave?
As a weak acid, the water is able to dissolve a small amount of the limestone rock as it passes through cracks and pores on its journey down into the cave. As this water drips into the air-filled cave, dissolved carbon dioxide is given off. Because the water has lost carbon dioxide, it cannot hold as much dissolved calcium.
How is calcium precipitated in Wind Cave?
The excess calcium is them precipitated on the cave walls and ceilings to make up many of the different kinds of formations. Most calcium is precipitated in the cave as the mineral calcite (CaCO3). The speloeothem that Wind Cave is most famous for is boxwork.
What to see in Wind Cave National Park?
Over 60% of Wind Cave National Park is unobstructed open grassland, allowing visitors to clearly see the abundance of wildlife that calls the park home. Bison frequently roam the prairie in such large herds that it’s unlikely to visit the park and not spot American bison.
