Horsetail Fall, located in Yosemite National Park in California, is a seasonal waterfall that flows in the winter and early spring. It flows over the east side of El Capitan, so as a backdrop it has one of the most impressive walls of granite in the entire park. Then during February something amazing happens. During middle to late February, when the sky is clear, the very last sunrays of the day selectively linger on the falls, lighting it up with a golden glow that makes the water look like lava.
The Yosemite Horsetail Firefall is a popular phenomenon. Each year hundreds of photographers and park visitors gather in the waning evening light for this amazing natural display.
