<p>wet curtain-like cave formations hang off a cave wall</p>
<p>This formation is named because of its resemblance to a mule's long ears. Draperies, flowstone, and dripstone are common cave formations seen all over the world, but are rare in Wind Cave due to the lack of water. The shape of these formations depends on the movement of water entering the cave.</p>
