Etched onto the surface of Lake Baikal, this snow and ice drawing is the world’s single largest artwork, stretching out to a total area of over nine square miles. The project took land artist Jim Denevan and his team of eight people 15 days to complete. Using the frozen black ice beneath the white snow as a canvas, Jim and his team used snow ploughs for the enormous circular lines and shovels for the smallest 18-inch circumference lines, Jim designed his pattern using a mathematical fibonacci curve and ‘drew’ his creation before the team began using a bike, which he rode around lining his artwork into the snow.
