Anti-waterfall? Spouting Horn, Hawaii
To complete the waterfall posts, here is a reverse action. Instead of falling down, this water leaps up.
Among the most photographed spots on the island of Kauai, this blowhole is caused by large swells of Poipu surf that enter a natural lava tube, then emerge with the hiss and roar that gave rise to the legend of the great lizard Kaikapu, guardian of this coastline.
