An artist from Somerset has walked more than 50 miles (80km) in circles wearing snowshoes to create vast snow drawings in Colorado.
Simon Beck, from Taunton, battled high winds and "very light" snow to create eight detailed designs in the freshly laid white stuff around Silverthorne.
The designs, which are best appreciated from above, are inspired by snowflakes, crop circles and mathematical fractals.
Mr Beck has set a personal record for the most designs created in one place.
The 61-year-old flew to Colorado at the beginning of January to pace out 10 giant murals, weather permitting, over the course of two weeks.
Best known for making huge geometric snow designs in the Alps with his feet, he said the snow in Colorado was different.
"It is very light due to the dry atmosphere in the interior of the continent, and it just blows about," he said.
"It doesn't seem to stick down into a snowpack as it does in the Alps."
The artist also had to battle high winds which "steadily removed" a lot of his work.
"There were two drawings that took a day and a half to make and the first was blown away," he said.
"And all the drawings were damaged to an extent by the wind. A quarter of my time was spent reinstating work I had done earlier."
The orienteering expert managed to stamp out eight massive snow murals across parks, the banks of a lake and baseball fields.
"I had seven volunteers at most helping me," he said.
"Shading is something anyone can do with 10 minutes practice but there is the danger they could make a mistake, so one has to keep an eye on them."
