Pogonip: the visual expression of clouds, wind and cold

In the freezing, windswept hours of late Thursday night, weather conditions in the Tehachapi Mountains turned the upper elevations white, like the hair of a mother worried about her grown but troubled children.

This phenomenon is known by several names, including Pogonip, which is derived from a Shoshone Indian word for “cloud.” Other terms include frozen fog or ice fog.

Jon Eric Hammond writes in the Tehachapi News on the lovely phenomenon called Pogonip. I've seen this myself a few times. It turns the landscape into a winter wonderland, and disappears quickly under the Sun's warmth.
