Firefall Will Glow Bright in Yosemite Until This Weekend

If you love unique natural phenomenon, hurry to Yosemite National Park or you’ll miss out on a true spectacle.

Called “Firefall,” this natural marvel appears to be lava flowing over a cliff at Yosemite, but it's not. It's an optical illusion. The "lava flow” is actually Horsetail Fall, a waterfall that looks like lava when the sun hits it at just the right angle.

This amazing sight is only available for a short time in February, drawing hundreds of witnesses every night. Firefall looks different every year depending on how much water flows from Horsetail Fall.

CNN spoke to Vaché Geyoghlian, a photographer from Fresno, California, who captured the scene on Monday night.

"My reaction was complete amazement," he told CNN. "I was overwhelmed with excitement to finally get to see it in person AND get some good shots of it too."

"My friend and I got to that specific spot at about 2:00-2:30 p.m. and we were the first ones there," Geyoghlian said. "That didn't last long as the entire area filled with hundreds of people looking to witness/photograph the 'Firefall.'"

This unbelievable sight is only available until this weekend when it will dissipate until next year.

"We have a designated parking area at Yosemite Lodge and visitors walk from there to the viewing areas," said National Park Service spokesman Scott Gediman.

Be sure to get there early, as the park will be crowded each night with lots of visitors.
