Land art or earth art is art that is made directly in the landscape, sculpting the land itself into earthworks or making structures in the landscape using natural materials such as rocks or twigs. 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. Richard Long , for example, simply walked up and down until he had made a mark in the earth. Other key land artists include Nancy Holt, Walter de Maria, Michael Heizer and Dennis Oppenheim. 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. [3]
In 1973, Robert Smithson died in an aircraft accident while he surveying sites in Texas for another Earthwork. The work "Amarillo Ramp" was completed by his widow and artistic partner, Nancy Holt. Smithson has a following among many contemporary artists. Artists Tacita Dean, Sam Durant, Renée Green, Lee Ranaldo, Vik Muniz, Mike Nelson, and the Bruce High Quality Foundation have all made homages to Smithson's works. In 2017 the Holt/Smithson Foundation was founded to preserve, through public service, the investigative spirit the two artists who "developed innovative methods of exploring our relationship with the planet, and expanded the limits of artistic practice."
