Led by artist Sonja Hinrichsen, a 50+ volunteers trace out these enormous swirling decorative designs on the frozen Catamount Lake in Colorado.

From her project statement:

It is important to me that participants experience the elements of nature while they help me transform their own familiar snow landscape into a piece of art. I hope that the aerial photographs that I take right after completion of each piece can demonstrate also to a larger audience how the landscape is transformed into a piece of art through a system of designs. This changes our perception of the landscape and accentuates the beauty and magic of the natural environment, and thus inspires awe and appreciation for art as well as for nature. I deem this important – especially as modern society becomes increasingly disconnected from the natural world.
