Every February, when weather conditions allow, Horsetail Fall on the eastern side of El Capitan appears to turn into a waterfall of fire or molten lava. It comes to life when the setting sun causes light to hit the waterfall at just the right angle. You can only see "Firefall" for a short time in February, and it draws hundreds of visitors to Yosemite National Park in California each night. How it looks varies from year to year, and relies on how much water is flowing in Horsetail Fall.
Yosemite Valley is a glacial valley in Yosemite National Park in the western Sierra Nevada mountains of Central California. The valley is about 7.5 miles (12 km) long and approximately 3000-3500 feet deep, surrounded by high granite summits such as Half Dome and El Capitan, and densely forested with pines. The valley is drained by the Merced River, and a multitude of streams and waterfalls flow into it, including Tenaya, Illilouette, Yosemite and Bridalveil Creeks. Yosemite Falls is the highest waterfall in North America, and is a big attraction especially in the spring when the water flow is at its peak. The valley is renowned for its natural environment, and is regarded as the centerpiece of Yosemite National Park, attracting visitors from around the world.
