Simon Beck creates large-scale artworks by walking through fields of snow. Working primarily in the Alps, he creates about 30 drawings each winter, shuffling through pristine snowfalls guided by a compass. A single image can require 10 hours’ time and 30 miles of of walking.

“Making these drawings is map-making in reverse,” he told the Guardian. “You start with the map, and you need to make the ground agree with the map.”
