Wind Cave National Park
Appearance
Established in 1903, Wind Cave National Park is a United States National Park in western South Dakota. It was one of the first U.S. National Parks 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. Aboveground, the park includes the largest remaining natural mixed grass prairie in the United States.
Several roads run through the park and there are 30 miles of hiking trails, so almost the entire park is accessible. The park had 850,000 visitors in 2003.
