Snow drawing…
Rabbit Ears Pass, Colorado
Step by step by snow-shoe’d step, this massive snow drawing was trampled into freshly fallen snow by artist Sonja Hinrichsen (with the help of 5 volunteers) last month… ephemeral art-making at its finest. Photos are by Cedar Beauregard and you can watch a beautiful aerial video sequence here.
