WIND CAVE

This lesser known National Park, tucked away below the Black Hills, is a cave with only one opening- a tire size hole on the side of a hill, which releases the wind for which it is named.

What is cool about this cave is that it was formed by standing water instead of moving water, so the walls are jagged, not smooth. As a result, the caverns are like swiss cheese, overlapping each other, creating vast amounts of passages in a very small area. Because of this, it is EXTREMELY easy to get lost in this cave, and it's not possible to enter without a guided tour.
