Rare self-rolling giant snow balls found in UK

They may look like winter's answer to crop circles, but these mysterious snow rolls are in fact a rare natural phenomenon usually found only in the world's most remote and frozen regions.

Also known as snowrollers, snow bales and snow doughnuts, they form mostly in unusual conditions created by a precise combination of snow, ice, wind, temperature and moisture on the prairies of North America.



But this week's frozen weather has allowed the snow cylinders to make a freak appearance in the UK.

Ron Trevett, 55, and his wife Aileen, 54, were stunned when they stumbled across the mysterious formations as they walked their dogs in a field near their home in Yeovil, Somerset.



"We saw them from a distance on the ridge of the field, and we thought some kids had been playing up there and making giant snowballs," said Mr Trevett. "But when we got up there we saw there were no footprints and there were hundreds of them – too many for children to have done it. We realised it must have been the wind."

Mr Trevett, a builder, said he and his wife felt privileged to have witnessed such a rare phenomenon. "We feel very lucky. I'm the wrong side of fifty and I've never seen anything like it in my life. We were gobsmacked to look at them there in the sunlight. It was a really impressive sight, and I took some pictures so other people could share it," he said.
