If you visit Yosemite at the right time in February and stay at the park till just before sunset, you'll see something you may not believe is real:
If there's enough snow and rain to fuel the waterfall, if the sky is totally clear and if the sun hits the water at just the right angle when it sets, the flowing water looks like flowing lava.
The phenomenon should continue for a few more days, so if you book a plane ticket or start driving right now, you might be able to glimpse it.
This is the first time in several years that the phenomenon has been so prominent, The New York Times reported. Previously, the drought in California had left the waterfall too dry.
