21 Feb 2013, Yosemite National Park, California, USA --- The natural fire fall on the rock formation know as El Capitan about to begin. The fire fall happens once a year during late February. A combination water falling from Horsetail fall, clear atmospheric conditions, and late afternoon sun are all needed to make the fire fall appear. Hundreds of nature watchers line up near El Capitan to see this phenomenon. --- Image by © Ted Soqui/Ted Soqui Photography/Corbis
