'Firefall' phenomenon wows visitors to Yosemite's El Capitan

California's Yosemite National Park is again wowing visitors and photographers with its annual "firefall."

Every February for a few days, the setting sun illuminates Horsetail Fall to make it glow like a cascade of molten lava.

The natural wonder draws scores of people to Yosemite Valley for a spot near the waterfall, which flows down the granite face of the park's famed rock formation, El Capitan.

Horsetail Fall only flows in the winter or spring, when there is enough rain and snow. In February, the sun lights up the fall for only about two minutes at dusk.

The best views are east of El Capitan along the main roads into and out of Yosemite Valley.

Park officials say the natural phenomenon is expected to last through the weekend.
