LEVITATED MASS chronicles the complicated transport and installation of a 340-ton granite boulder to be used as part of an art piece outside the Los Angeles County Museum of Art. This film shows the rock’s 105-mile journey, which challenged the imagination of thousands of Southern Californians, and the spectacle of the sculpture’s construction. It weaves together the dramatic story of artist Michael Heizer's past and present work, the ambitions of a major metropolitan museum, and the public's wild reactions to this massive display of ancient-feeling modern art.
