Yosemite National Park is one of America’s most beautiful areas. The park is well-known for its incredible natural formations and views. It consists mainly of a broad valley in the Sierra Nevada region and attracts millions of visitors every year.
One of the most famous sights of Yosemite National Park is only visible for a couple of weeks out of the year. It’s called Firefall, and people travel all the way to Yosemite to see it. The natural phenomenon appears to be hot, glowing lava flowing against a cliff. Firefall is an optical illusion that occurs when the sun is at a particular place in the sky. When the sun hits Horsetail Falls in just the right way, it transforms into Firefall. The regular waterfall becomes a spectacular sight every year near the end of February.
This year, Firefall is around for the rest of this week. During that time, photographers and nature lovers flock to viewing areas to catch a glimpse of Firefall. Park employees even set up special viewing areas every year to accommodate all the visitors. Each night as the sun goes down, the areas get crowded with hundreds of people.
One of the most intriguing things about Firefall is that it never looks the same twice. Every year, there are differences in its appearance depending on the amount of water flowing. The sight is available for just another couple of days until the sun changes positions slightly and the light doesn’t hit the water just right.
The phenomenon has so many specific conditions that it’s not quite the same even at other times of year when the sun shines down on Horsetail Falls. The water has to be thawed enough to be flowing freely, and the sky has to be free of clouds right at sunset.
