Land art is made directly in the landscape, sculpting the land into earthworks or making structures using natural materials found in the landscape such as rocks or twigs
Land art was part of the wider conceptual art movement in the 1960s and 1970s. The most famous land art work is Robert Smithson’s Spiral Jetty of 1970, an earthwork built out into the Great Salt Lake in the USA. Though some artists such as Smithson used mechanical earth-moving equipment to make their artworks, other artists made minimal and temporary interventions in the landscape such as Richard Long who simply walked up and down until he had made a mark in the earth.
Land art was usually documented in artworks using photographs and maps which the artist could exhibit in a gallery. Land artists also made land art in the gallery by bringing in material from the landscape and using it to create installations.
Land art is also known as earth art.
