‘Firefall’ lights up Yosemite National Park

Shutterbugs are descending upon Yosemite National Park this week to capture a natural phenomenon known as a firefall.

For two weeks in February each year, the sun strikes Horsetail Fall at exactly the right angle to make the waterfall glow like a river of fire.

The sight is especially rare since Horsetail Fall only flows after enough rain and snow has fallen, which storms in the area this past month seem to have guaranteed.

It’s also only visible for a few minutes after sunset every day, but that hasn’t stopped photographers from showing up hours early to reserve the best viewing spots.
