'Firefall' Shimmers Like Lava in Yosemite Sunset

A waterfall in Yosemite National Park glowed bright orange on February 21 as it was lit up by the setting sun.

Depending on weather conditions, the “Firefall” phenomenon occurs annually for a number of days in February. The light of the sunset hits Horsetail Fall at just the right angle to give the waterfall the appearance of molten lava.

There must also be enough melting snow to feed Horsetail Fall for it to light up, according to yosemitefirefall.com.

The National Park Service required visitors to make a reservation to watch this year’s event due to COVID-19 restrictions. Credit: Emilie Hofferber via Storyful
