Below the remnant island of intact prairie in South Dakota sits Wind Cave, one of the longest and most complex caves in the world and the first cave to be designated a national park. Named for barometric winds at its entrance, this maze of passages is home to boxwork, a unique formation rarely found elsewhere.
Along with this massive cave, Wind Cave National Park also features 28,295 acres of mixed-grass prairie, Ponderosa pine forest, and wildlife.
