Horsetail Fall, a 1,000-foot (305-meter) waterfall, appears like lava at sunset as it pours over the granite face of El Capitan in Yosemite National Park, California. The dramatic lighting effect, which has been called a "firefall," appears in mid-to-late February if the weather conditions are just right.
