In this February 2008 photo provided by Scott Gediman of the Yosemite National Park Service, the setting sun hits Horsetail Fall at just the right angle to light it up as if it's on fire, in Yosemite Calif. This natural phenomena occurs for just two weeks in February and is reminiscent of the old firefall of burning embers that park employees pushed over Glacier Point to entertain guests until 1968.
