In the category of whoa! And a link to how to photograph it, here… this seems to be a natural version of a ritual where people used to actually push a pile of burning embers off a cliff. Sounds like a good way to start a forest fire to me, but hey who am I right?
The Firefalls of Yosemite Park are a natural phenomenon that occurs during a two week period every year. Set in the Yosemite Valley, itself part of the Sierra Nevada mountain chain in California, this has to be one of the most beautiful and fiendishly rare natural sights in the world. As the sun sets on the Yosemite Valley, the Horsetail Waterfalls of El Capitan are illuminated from behind by the red glow of the light rays, turning them into a huge and spectacular optical illusion – as if fire were raining down from the top of the cliffs.
