Falling flames

Last year, Yosemite National Park's famed "firefall" was more of a "firedrizzle" due to lack of snow. But this year, the "firefall" is burning bright.

Yosemite's Horsetail Fall flows like lava under a clear sky and favorable lighting. It's a small waterfall that makes big news whenever it glows orange during sunset in mid- to late February.

When that happens, the waterfall will glow orange for about 10 minutes.
