Levitated Mass

In December 2006, Heizer discovered a rock at Stone Valley Quarry in Jurupa Valley (Riverside County, California). With the help of LACMA director Michael Govan, funding was secured for the boulder's removal and transportation and for the construction of the finished work at the museum. The cost of the project has been estimated at $10 million, and was funded entirely via private donations.

The 340-ton boulder is affixed above a concrete trench through which visitors may walk. The nature, expense and scale of the installation made it an instant topic of discussion within the art world.

The artwork, with the boulder at its center, now presides over the museum grounds north of the Resnick Pavilion.
