The Sandbar Willow is the most distinctive willow in the park. This is because of the narrowness of its leaves and its habit of forming thickets from sprouting from rhizomes. American Indians used it slender, pliant stems to make sweat lodges and baskets.

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.
