These snowy 'crop circles' are in fact the work of a lone artist who has spent hours, and a whole lot of effort, trudging around a French ski resort.
The patterns, some of which span the size of six football pitches, come in a range of designs from intricate snowflakes and spirals to cubes and rather more abstract creations.
'The main reason for making them was because I can no longer run properly due to problems with my feet, so plodding about on level snow is the least painful way of getting exercise.
'Gradually, the reason has become photographing them, and I am considering buying a better camera.'

Mr Beck, who studied Engineering Science at Oxford University, said the designs were created at the Arc2000 ski resort in Savoie, France.
Many take as long as five hours to construct and can equal the effort needed to climb halfway up Mount Blanc, he said.
He added: 'I usually keep at it until I get too tired, using a headlamp if it gets dark first. It takes typically five hours until I can't go on, but that can depend.
'The setting-out serves as the warm-up then the real training is completing the design. Once this second stage is started, I put on my personal stereo.'
