These odd circles may look like messages from aliens or the humorous graffiti of penguins, but it’s actually the ephemeral snow and ice art of earth artist Jim Denevan, best known for his temporary beach masterpieces. The snow circles are somewhat of a departure from Denevan’s usual medium, but he’s no stranger to large-scale natural art. This nine-square-mile snow drawing currently holds the record as the world’s largest snow drawing; the record before that belonged to a sand drawing created in the Nevada desert by Denevan.
