Is that a word?
Yes, it is. A word I had never heard until the other day when my son said that was what we were having with the snow, fog and ice--a pogonip.

I had to come home and look it up. And find pictures of it. It's beautiful! What is it?
The Old Farmer's Almanac offers a definition of the pogonip as "ice fog," noting that the word is believed to have originated from a Native American word. Apparently the pogonip is reserved for the valleys of the western US.
I found more complete information and theories about the origin of the term at WordInfo. This author links the term to Greek, not Native American, origins. The photos included in the article are stunning.
Are there any Westerners reading this who can offer more information about this unusual word and the type of frost it describes? Is it the same thing as hoarfrost? Or is there more to the pogonip?
