Earth Art

Earth Art is a type of art in which elements of an environment are used as the means of creation. Earth artists may use naturally occurring materials, including dirt, stones, leaves, and vegetation, to create works that either exist fully in nature or are shown in galleries. Alternate media, like photography and video documentation, is often used as a way of preserving the piece.
Also named Land art, Earthworks, or Environmental Art, Earth Art became popular in the 1960s and 70s, particularly with the increase in environmental awareness and concern. Some well known earth artists include Robert Smithson, famous for his Spiral Jetty, Andy Goldsworthy, and James Turrell. The Nazca Lines in Peru and Stonehenge in England are ancient examples of site-specific creations.
