National Park Week: Wind Cave National Park

Hidden below the prairie at Wind Cave National Park, you’ll find something unexpected: one of the longest caves on the planet. This site includes 140 miles of explored passageways. What’s above ground is equally special, as the prairie supports one of the most genetically pure herds of bison in the country.
