How Do People React To The Real-Life Optical Illusion In California?
In February, tourists and nature enthusiasts gather at California‘s Yosemite National Park to witness a stunning optical illusion that manifests just once a year, lasting for a few weeks during that month.

The place has become a rather famous tourist destination as Instagram influencers and other aesthetic hunters travel to the destination to get the perfect picture for their social media followers and experience the brilliance of the Yosemite Firefall.
Why Is It An Optical Illusion?
Back in 1872, the owners of the Glacier Point Hotel, which had a view of Yosemite Valley, used to toss bonfires into a natural waterfall. Their aim was to create the illusion of molten lava cascading down a cliff.

However, little did they know that if they had waited for the perfect weather conditions, specifically the late February sunlight just before sunset, the Yosemite Firefall would naturally appear as if it were erupting in golden flames instead of water. This enchanting sight was quite different from the artificial firefall they had created to attract visitors.
Every February, an official Yosemite Firefall event is organised, which invites visitors to witness a completely natural optical illusion that requires no human intervention at all.
What Is The Truth Behind The Phenomenon?

When the sun sets at a specific angle, its rays precisely touch Horsetail Falls in the park. This unique angle illuminates the falls, producing a breathtaking illusion that resembles flowing lava or cascading fire. The occurrence of this illusion is dependent on various factors, such as weather conditions and the water levels at the falls.
The science behind the phenomenon is pretty simple, yet the illusion is absolutely magical. The backlight from the sunset gives the impression that the slender waterfall is flowing like molten lava along the eastern side of El Capitan. The intense radiance is so striking that numerous individuals have come across photos and questioned whether Yosemite Firefall consists of an actual fire. Fortunately, it isn’t, but the impact is truly astonishing.
However, it is not an everyday treat for the eyes. Mother Nature doesn’t make any guarantees when it comes to staging a Firefall spectacle. It might be a clear day with the waterfall flowing down the mountainside, but if clouds move in just before sunset, the Firefall won’t happen. Since the Firefall typically occurs in the moments leading up to sunset, a clear sky is essential for the sunlight to penetrate the valley and illuminate Horsetail Fall.
