FILE - In this June 9, 2011 file photo, Stephen Vander Hart, co-owner and vice president of Stone Valley Materials, walks past a 340-ton boulder from his quarry in Riverside, Calif. After months of preparation, the giant chunk of granite that acclaimed earth artist Michael Heizer selected to be the centerpiece of his latest creation is scheduled to leave the quarry late Tuesday night, Feb. 28, 2012. From there it will make a circuitous, 105-mile journey to the Los Angeles County Museum of Art's backyard, where it is to become the focal point of Heizer's "Levitated Mass."
