Beginning in the 1960s, a group of artists, many seeking to escape the commercialism of Pop Art, adopted a new canvas: the earth. Some, like Richard Long and Patricia Johanson, designed minimalist landscape interventions, while others, like Michael Heizer and Robert Smithson, used backhoes to sculpt land into monuments that rival Mayan ruins in grandeur.
"Ends of the Earth," at the Geffen Contemporary at the Museum of Contemporary Art, Los Angeles, traces the birth of the movement. Opens April 8; moca.org
