Natural Entrance of Wind Cave

Winds caused by changes in barometric pressure are what give Wind Cave its name.  These winds have been measured at the cave's walk-in entrance at over 70 mph. The winds at the natural entrance of the cave attracted the attention of Native Americans and early settlers.
