The illusion, nicknamed "firefall" because it makes the waterfall appear to be flowing fire, is noted each year at the park when the angle of the sunset reflects off the water.

It falls off of the east side of El Capitan and is best seen from just east of El Capitan," Yosemite National Park's website states. Many photographers shared images on social media of the firefall as seen from the El Capitan picnic area in California.
