It's almost time for Mother Nature to play her annual magic trick at Yosemite National Park.
In the impressive yearly display, a light trick makes it appear as if lava is flowing off a cliff.
"Firefall" is the name for the phenomenon that creates the illusion at the park in California.
It comes to life when the setting sun causes light to hit the waterfall at just the right angle.
You can see "Firefall" for only a short time in February, and it draws hundreds of visitors each night.
