The Horsetail Fall（瀑布） is one of Yosemite National Park's most amazing views. Around the second week of February, the setting sun hits the Horsetail Fall at just the right angle（角度） to light the upper parts of the waterfall. And when conditions are right, the Horsetail Fall becomes orange and red at sunset. It is like red-hot lava（熔岩） pouring down from the top of the El Capitan. So, it got the name "firefall".
The firefall is a perfect match of the weather, the fall, the time and the watching place. It usually appears on dry, warm and cloudless days. There must be enough flowing water to make a firefall too. So there must be enough snow on the mountain top, and it turns into water on warm afternoons.
The sun goes to the best place before the fall in late February. And the best time to watch the fall is 5 to 15 minutes before the sunset. Only at this time can visitors see the firefall. The El Capitan Picnic Area is the best place to watch, because it is close to the fall and is perfect to set up cameras and tents.
Every year in February, thousands of photographers come to watch the firefall. Although the view may appear just minutes before sunset, many of them have to come hours earlier to get a right place to set their cameras in time. "I'm just saying that the Yosemite Firefall is something you don't want to miss during the winter," says Kate Moore, a traveller.
