Wind Cave is distinctive for its calcite fin formations called boxwork, a unique formation rarely found elsewhere, and needle-like growths called frostwork. It is one of the longest caves in the world and creates a wind as air pressure changes. Above ground is a mixed-grass prairie with animals such as bison, black-footed ferrets, and prairie dogs and ponderosa pine forests home to cougars and elk.[113]The cave is culturally significant to the Lakota peopleas a creation site. -Wikipedia
