Levitated Mass

The Levitated Mass project is an artwork installation, by American artist Michael Heizer, located on the Los Angeles County Museum of Art campus.  The art piece consists of a 340-ton, 21’-6” tall monolithic granite boulder, placed over a 15- x 450- foot concrete trench, which descends fifteen feet into the earth.  The boulder was discovered by the artist in a quarry in Riverside County after it fell 180 feet without breaking.  The project team worked closely with the City to obtain permits for the structural support of the boulder, being the first project of its kind in Los Angeles.  Approximately 2.5 acres of new landscaping and site work surrounds the artwork.
