Firefall at Horsetail Fall, Yosemite National Park, California

Firefall stuns at Yosemite. A natural light show

Travel to Yosemite National Park in California’s Sierra Nevada mountains during February and you may be shoulder-to-shoulder with photographers hoping to get a shot of Horsetail Fall in the evening. When conditions are right, rays of the setting sun align with the falling water to set the cascade ablaze with light - a natural display called the ‘firefall.’ And in a bit of added mystique, Horsetail Fall itself is an ephemeral waterfall - it flows only for a short time in the winter and early spring.
