These intricate patterns in the snow are not the work of cold–weather aliens, but of artist Simon Beck, a "snow artist" who spends hours creating these massive designs by walking very, very carefully. Each final piece is the size of three soccer fields. More of Simon's work is below, along with the work of another snow artist, Sonja Hinrichsen.
Sonja Hinrichsen created these large-scale "snow drawings" below, at Rabbit Ears Pass in Colorado with the help of five volunteers. Check out more of Sonja's work in the videos!
