[tocqueville]

‘I hadn’t seen them on my morning drive, so they must have formed in the space of a few hours,’ said Mr Tevebaugh, who witnessed the scene eight miles east of Craigmont.

Each frozen hay bale-like formation was up to about 2ft high and not a single footprint could be seen surrounding them.

But despite claims of alien interference, snow rollers are understood by experts to be an extremely rare naturally occurring phenomenon.

They require just the right combination of temperature, humidity, wind speed, terrain and of course, snow.
