First of all, you might be wondering what a fire rainbow is, aside from a concept you might find in a fantasy novel. Fire rainbows are real, and they're radical. Check out this one, photo snapped by Derrick Blake, a graphic designer in Salt Lake City:

A fire rainbow is a rare cloud phenomenon that only happens during the summer, when the sun is very high in the sky, said Monica Traphagan, a meteorologist for the National Weather Service in Salt Lake City. The sunlight goes through the ice crystals in the cirrus clouds and creates what looks to us like a rainbow, Traphagan said.

Normally, you would see the rainbow form a halo — but because the cirrus clouds were sparse over the valley, and the sun needs them as a sort of "canvas," the rainbow effect only showed up in a patch.
