Artist Sonja Hinrichsen, together with 5 volunteers last month created, step by step, these massive ‘snow-circles’ into freshly fallen snow at Rabbit Ears Pass in Colorado.
The five friends created the snow-circles simply walking with snow boots around the pristine snow. Three hours later local photographer Cedar Beauregard took this aerial footage with a camera mounted on a remote-controlled hexacopter. Detailed photos can be seen here.
