When fog (visible water vapor near the ground) freezes it's called frost...
snow is different, snow is the inverse.

One of the most amazing things that can happen on a cold morning is a
freezing fog leading to rime frost on trees. I've most often seen this in the
river vally just north of my house.

It's staggeringly beautiful, but usually quite ephemeral, when the sun is
shining; millions of rainbow crystals glittering in the morning light.

Thank you for the lovely photos and very informative articles.

Your pictures remeinded me that I have some similarly depicting the frost
phenomena, not nearly as artistic:

My "Fat Albert" Colorado blue spruce's first Christmas (2008):

Here it is at night... at first I was suprised,
until I realized the flash made the otherwise
invisable water vapor appear, eerie:

My new spruce is now covered with buds that weren't there last fall, albiet
still tightly closed, very exciting waiting to see the progress.

You are most certainly welcome.

I wish I had done more than found them on the web. I did pick them
out of thousands, though.

Nice bit of land you've got there.

Ah, I think you posted this one before! I like the misty effect.


My new spruce is now covered with buds that weren't there last fall, albiet
still tightly closed, very exciting waiting to see the progress.

I finally found a crocus blooming near the SE corner of the garage.
April already, and the snowdrops are still in bloom. The buds are
finally showing some sign of swelling on the amelanchier.

We had one warmish day last month. Today is supposed to be warm,
but I have commitments all day. And this weekend it will be turn
COLD again. So the outside gardening is running behind.

Meanwhile, inside I'll be gearing up to start the tomatoes, eggplants,
and peppers (and here's hoping we don't have a repeat of the late May
hard frost this year).
