According to Wikipedia:
Michael Heizer (born 1944) is an American land artist specializing in large-scale and site-specific sculptures. Working largely outside the confines of the traditional art spaces of galleries and museums, Heizer has redefined sculpture in terms of size, mass, gesture, and process. A pioneer of 20th-century land art or Earthworks movement, he is widely recognized for sculptures and environmental structures made with earth-moving equipment, which he began creating in the American West in 1967. He currently lives and works in Hiko, Nevada, and New York City.
