Artist Sonja Hinrichsen enlisted five volunteers create beautiful geometric forms in the snow with their footprints. Cedar Beauregard, a cinematographer specializing in aerial photography, captured this footage of the piece with a remote-control helicopter, as well as these still images on Flickr.

In her artist statement, Hinrichsen describes the broader goals of her work: 

As an artist I feel the responsibility to direct attention to subject matters our society neglects or denies, including adverse impacts to the natural environment, social inequality and injustice, and human exploitation. Lately my works have often included interventions or rituals that I perform in the environment. These are documented photographically and on video, which then becomes integrated in media installations. The traces left in the environment are non-permanent and any evidence will be erased by nature. While I like to unfold my work in large immersive experiences using digital media, I am not interested in creating lasting art pieces, as I believe that our world is over-saturated with man-made products. However, as an environmentalist I hope that I can inspire appreciation and awe for our natural world.
