For two weeks in mid to late February, spectators visiting Yosemite's El Capitan, a notable rock formation in Yosemite Valley, are in for a dazzling experience. When the sun hits Horsetail Fall at the right angle, the waterfall lights up as if it's on fire, CBS News reported.
The orange glow, however, doesn't happen every year. It's dependent on conditions like water flows, clouds, and temperature.
“[It’s] this thin ribbon of water just glowing orange with the cliff and the shade behind it, so it just seems like it has its own source of light that there’s nothing else creating it. It’s really an amazing and beautiful thing to see,” photographer Michael Frye told the National Park Service.
