In 2009, when artist Sonja Hinrichsen was in Snowmass Village for an artist's residency, she took a walk in the snow with a new pair of snowshoes, and started to mess around.
"It started just out of play, walking patterns into fields of snow. There is a pretty big golf course in that area…and nobody would go there."
Hinrichsen later got her camera and photographed her patterns. That's when she realized "this amazing thing. Depending on where I was with my camera in relation to the sunlight, I got a white line in the snow or I got a dark line in the snow."
