Yosemite 'firefall' has hikers transfixed

Sangeeta Dey said she was touched and overwhelmed by how much attention her photo had received

A rare phenomenon known as "firefall" has drawn visitors and photographers to Yosemite National Park in California.

The stunning visual display happens every February when the light hits a waterfall tumbling down El Capitan.

But the intensity of this phenomenon depends on the volume of water and the cloud cover.

The park authorities said: "The Horsetail Fall phenomenon appears when the angle of the setting sun sets the waterfall ablaze with reds and oranges, like a fire was falling down the cliffs on the shoulder of El Capitan."

Here is how some photographers captured it.
