Around this time of year – if the western horizon stays clear – the last few minutes of daylight fall perfectly on Horsetail Falls, making it glow as if on fire. Photographers call it the firefall …
Mike Mezeul II wrote to EarthSky:
For two weeks out of the year, a spectacular event known as the firefall takes place within Yosemite National Park. Hundreds if not thousands of photographers flock to the valley in hopes of capturing the elusive moment, that is, if the weather, snow and light cooperate. If Yosemite receives an ample amount of snowfall throughout the winter, and if the western horizon stays clear, the last few minutes of daylight fall perfectly upon Horsetail Falls and illuminate it in a vibrant orange and red. The waterfall glows so fiercely that it appears to be on fire. Yesterday, after the valley received several feet of snow for a few days, one last clearing snowstorm led to the perfect mix of ingredients. Water flowing from the beautiful Horsetail Falls and a dazzling mix of broken clouds floating past El Capitan as the sunset set the fall ablaze.
Thank you, Mike!
Bottom line: Fireball at Yosemite National Park, February 17, 2019.
