Dian Parker wrote in ArtNet, "The artist’s ecological message seems more timely now than ever, noted Adam Weinberg, the director emeritus of the Whitney Museum of American Art.
[11] In 1967, the art critic Grace Glueck writing in The New York Times declared the first Earthwork to be done by Douglas Leichter and Richard Saba at the Skowhegan School of Painting and Sculpture.
[12] The sudden appearance of land art in 1968 can be located as a response by a generation of artists mostly in their late twenties to the heightened political activism of the year and the emerging environmental and women's liberation movements.
One example of land art in the 20th century was a group exhibition called "Earthworks" created in 1968 at the Dwan Gallery in New York.
Gordon Matta-Clark, who lived in Ithaca at the time, was invited by Sharp to help the artists in "Earth Art" with the on-site execution of their works for the exhibition.
[16] Smithson's Gravel Mirror with Cracks and Dust (1968) is an example of land art existing in a gallery space rather than in the natural environment.
[17] "Land artists" have tended to be American,[2] with other prominent artists in this field being Carl Andre, Alice Aycock, Walter De Maria, Hans Haacke, Michael Heizer, Nancy Holt, Peter Hutchinson, Ana Mendieta, Dennis Oppenheim, Andrew Rogers, Charles Ross, Alan Sonfist, and James Turrell.
Turrell began work in 1972 on possibly the largest piece of land art thus far, reshaping the earth surrounding the extinct Roden Crater volcano in Arizona.
Perhaps the most prominent non-American land artists are the British Chris Drury, Andy Goldsworthy, Richard Long and the Australian Andrew Rogers.
Rogers' “Rhythms of Life” project is the largest contemporary land-art undertaking in the world, forming a chain of stone sculptures, or geoglyphs, around the globe – 12 sites – in disparate exotic locations (from below sea level and up to altitudes of 4,300 m/14,107 ft).
