What is Earth Art?

Natural or man-made, the central focus of earth art is to produce a work that accentuates or produces a viewpoint of nature. Artists often build or sculpt using natural materials including rocks, soil, sediment, plants, or other natural features of terrain. Objects found in nature can be manipulated to represent an artist's expression, while others choose to capture natural phenomena using specialized lenses and other media of photography. Earth art provides a way that artists can express themselves in one of the purest, or perhaps most grounded, fashion. This to me is what encompasses earth art.
