Wind Cave National Park is a United States national park 10 miles (16 km) north of the town of Hot Springs in western South Dakota. Established in 1903 by President Theodore Roosevelt, it was the seventh U.S. National Park and the first cave to be designated a national park anywhere in the world. The cave is notable for its displays of the calcite formation known as boxwork. Approximately 95 percent of the world's discovered boxwork formations are found in Wind Cave. Wind Cave is also known for its frostwork. The cave is also considered a three-dimensional maze cave, recognized as the densest (most passage volume per cubic mile) cave system in the world. The cave is currently the sixth-longest in the world with 139.15 miles (223.94 km) of explored cave passageways, with an average of four new miles of cave being discovered each year. Above ground, the park includes the largest remaining natural mixed-grass prairie in the United States.
Early knowledge 
The Lakota, Cheyenne, and other Native American tribes who traveled through the area were aware of the cave's existence, as were early Euro-American settlers, but there has been no evidence yet discovered that anyone actually entered it.
The Lakota (Sioux), an indigenous people who live in the Black Hills region of South Dakota, spoke of a hole that blew air, a place they consider sacred as the site where they first emerged from the underworld where they had lived before the demiurge creation of the world.
The first documented discovery of the cave by White Americans was in 1881, when the brothers Tom and Jesse Bingham heard wind rushing out from a 10-inch (25 cm) by 14-inch (36 cm) hole in the ground. According to the story, when Tom looked into the hole, the "wind" (exiting cave air) blew his hat off of his head.
Source of cave's name 
Caves are said to "breathe," that is, air continually moves into or out of a cave, equalizing the atmospheric pressure of the cave and the outside air. When the air pressure is higher outside the cave than in it, air flows into the cave, raising cave's pressure to match the outside pressure. When the air pressure inside the cave is higher than outside it, air flows out of it, lowering the air pressure within the cave. A large cave (such as Wind Cave) with only a few small openings will "breathe" more obviously than a small cave with many large openings.
Rapid weather changes, accompanied by rapid barometric changes, are a feature of Western South Dakota weather. If a fast-moving storm was approaching on the day the Bingham brothers found the cave, the atmospheric pressure would have been dropping fast, causing the cave's higher-pressure air to rush out all available openings, creating the "wind" for which Wind Cave was named.
Early exploration and tours 
From 1881 to 1889, few people ventured far into Wind Cave. Then in 1889 the South Dakota Mining Company hired Jesse D. McDonald to oversee their "mining claim" on the cave site. The South Dakota Mining Company may have hoped to find minerals of value, or it may from the start have had commercial development of the cave in mind.
No valuable mineral deposits were found, and the McDonald family began developing the cave for tourism. Jesse initially hired his son Alvin (age 16 in 1890) and, beginning in 1891, Alvin's brother Elmer, to explore and help develop the cave. Alvin fell in love with the cave and kept a cave diary. Others who worked at Wind Cave and helped explore it between 1890 and 1903 include Katie Stabler, Emma McDonald (Elmer's wife), Inez McDonald (Emma and Elmer's daughter), and Tommy McDonald (brother of Elmer and Alvin).
Tourists, with their guide, explored the cave by candlelight. These early tours were physically demanding and sometimes involved crawling through narrow passages.
Like the nearby Jewel Cave National Monument, currently the second longest cave, Herb and Jan Conn played an important role in cave exploration during the 1960s.
Surface resources 
Wind Cave National Park protects a diverse ecosystem with eastern and western plant and animal species. Some of the more visible animals include elk (also called wapiti), bison, black-footed ferrets, pronghorn and prairie dogs. The Wind Cave bison herd is one of only four free-roaming and genetically pure herds on public lands in North America. The other three herds are the Yellowstone Park bison herd, the Henry Mountains bison herd in Utah and on Elk Island in Alberta, Canada. The Wind Cave bison herd is currently brucellosis-free.
Several roads run through the park and there are 30 miles (48 km) of hiking trails, so almost the entire park is accessible. The park had an estimated 577,141 visitors in 2010.
The Wind Cave Visitor Center features three exhibit rooms about the geology of the caves and early cave history, the park's wildlife and natural history, and the work of the Civilian Conservation Corps in the park.
Elk Mountain Campground, located in a ponderosa pine forest, is about 1.25 miles (2.01 km) from the visitor center. There are 75 sites for tents and recreational vehicles. It is open year round with campfire programs offered in the summer and limited services available in the winter. As of March 2013, the campground has been closed due to budget cuts stemming from the United States budget sequestration law. However, the decision to close the campground was reversed, and it will be available starting May 24, 2013.
