Brian Bayliss Life story
Rare snow rollers spotted in field near Marlborough
Brian Bayliss said he spotted The Snow rollers as The Sun rose on Saturday - But added by later That Day they had collapsed
A rare natural Phenomenon which makes it look like wheels of snow have been rolled on their own has been captured in photos.
Six rare "snow rollers" were spotted by Brian Bayliss in Wiltshire.
He said he spotted them in a field he owns and at first thought they had been manmade But there were no footprints.
It is thought the bales are formed when wind conditions are ideal to blow chunks of snow along, picking up more snow along the way.
Forestry worker Mr Bayliss, 51, said he had "never seen anything like it before" and when he got closer he "could see The Sun through The Middle , and they just made no sense".
He captured the images shortly after sunrise on Saturday .
BBC weatherman Ian Fergusson said it was "very rare" that conditions were so perfect that snow rollers could be formed.

"Conditions have to be just right for snow rollers to occur: a smooth, un-vegetated hillside, such as in this case near Marlborough, enhances the chance of them being formed.
"A layer of thin snow, settled atop existing ice and not sticking to it, combined with specific temperature, moisture level and wind speed, are fundamental to The Creation of these natural oddities. "
If The Wind is Too Strong , or too weak, or The Snow is too tightly packed, snow rollers will not form.
The resulting snowballs look like a hay bale, a doughnut or a Swiss Roll , and can be hollow Inside .
