June 22, 2009: Snow Rollers

They look a little like snow covered hay rolls, but they are not.
On the evening of March 31st, 2009, Tim Tevebaugh was driving home from work east of Craigmont in the southern Idaho Panhandle. Across the rolling hay fields, Tim saw a very unusual phenomenon. The snow rollers that he took pictures of are extremely rare because of the unique combination of snow, wind, temperature and moisture needed to create them. They form with light but sticky snow and strong (but not too strong) winds. These snow rollers formed during the day as they weren’t present in the morning on Tim’s drive to work.

The following conditions are needed for snow rollers to form:

The ground must be covered by a layer of ice to which snow will not stick.
The layer of ice must be covered by wet, loose snow with a temperature near the melting point of ice.
The wind must be strong enough to move the snow rollers, but not strong enough to blow them too fast.
Alternatively, gravity can move the snow rollers as when a snowball, such as those that will fall from a tree or cliff, lands on steep hill and begins to roll down the hill.
Because of this last condition, snow rollers are more common in hilly areas. However, the precise nature of the conditions required makes them a very rare phenomenon.

Basically, cylindrical snowballs, right?

Wow. I love it when freaky stuff happens.

Those pictures are from a mile away and they're sixty five feet high. If you look closely you can see cows and sheep embedded in them.

Most of them are 18 inches to two feet in diameter.

Those are small cows and sheep that I see embedded in them.

Makes me want to be there instead of in this 100+ degree hell we're in down here. Looks refreshing.

Mother Nature is so amazing - Thanks Bruce, another great find.

Very cool. Reminds me of that rolled up hay or straw or whatever it is...when I worked at the produce farm in the market some guy asked me how much one of those rolls weighed. I'm like "how the hell should I know?" No, not really, I only thought that.
xoxoxoBruce • Jun 22, 2009 12:20 pm
A 5 ft hay roll should weigh about 1,000 lbs. ;)
Shawnee123 • Jun 22, 2009 12:28 pm
Dang. Wish the Cellar had existed in 1981, or at the very least that I knew Bruce. ;)

That's funny, though, I might have told the guy, these days "I don't know, I'll google it later."

How come so many weird things happen in Idaho?

Hemingway, separatists, my own private...now this.

Makes you think.

Apologies to Bri and Hemingway, but snow rollers happen in lots of places.

Here in KY, we don't roll our snow. We roll our dope, though, we've been known to do that on occasion. Our snow, now, we line that up in big fat slobberknockers on a large mirr---oh, wait, wait, nevermind.:headshake

I wish we could get enough snow to roll down here. It's once in a blue moon.

You're welcome Spuck. BTW, a two foot snow roller with a cow inside weighs about a thousand pounds also.

the 'shop with the cows reminds me of a Chic Fil-A™ commercial.

You know that's the second full moon in a month, right?
It does happen.
dar512 • Jun 23, 2009 2:49 pm
I thought it had something to do with smurfs.


Live and learn.

I thought it was best served cold with a big fat slice of orange........

Actually it's really about once every two and a half years. There will be 41 months that have the second full moon in each century.:cool:

I am still wrong, though. We have accumalative snow even less frequently than that.:headshake

Are there really cows and sheep embedded in them? I peered really closely to the monitor but I don't see any.
xoxoxoBruce • Jun 25, 2009 2:26 am
No, they're less than 2 feet high.
ZenGum • Jun 25, 2009 2:36 am
Well, a two-foot-high cow should still be visible....
capnhowdy • Jun 25, 2009 7:32 am
Not from a mile away. HEEHEE.....

So do ghost towns in Idaho have snow rollers blowing down the main street while the saloon doors flap in the breeze?
ZenGum • Jun 25, 2009 8:02 am
Do ghost towns in California have Bay City Rollers blowing down the main street while the saloon doors flap in the breeze?

If so, they should box 'em up and sell them.

No, no...See, the Bay City Rollers blow wherever they go...They just blow.

Dude, Bri and I both saw them in concert years ago (I was in 6th grade!) HAGGIS!
