LAND ART, also known as earth art, is art in which the landscape or natural elements often form the basis for the artwork. Artists may create artworks directly in the landscape, utilizing their natural surroundings and integrating the landscape itself into their work. Conversely, artists may also incorporate natural elements into works exhibited in gallery spaces. Land Art emerged in the southwestern United States during the late 1960s, and culminated in the mid-1970s. Since the 1970s, much Land Art has been absorbed into the broader realm of Environmental Art, as many artists began working in more urban and public spaces. Today, Land Art remains an integral part of Environmental Art, with artists practicing in many places around the world including Japan, South Africa, the Middle East, and Australia.

Walter de Maria established his reputation as a prominent American Land Artist in the late 1960s with his debut of The New York Earth Room, a now legendary installation. For the piece, de Maria filled three adjoining gallery rooms with a 60 cm deep mass of soil. Leaving only a small viewing area at the gallery entrance, viewers look out into the rooms filled with earth, but are prevented from entering the rooms. In what is perhaps his most famous work, The Lightening Field (1977), de Maria meticulously arranged 400 vertical steel rods in a 1 mile x 1km grid atop a remote plateau north of Quemado, New Mexico. The work is said to be most spectacular during thunderstorms when lightening strikes the rods.
