Elizabeth Kuder, an artist and admirer of Heizer's work, strolled over from her house a few blocks away to snap photos of the site. Kuder said she believes the journey itself was part of Heizer's vision, pointing out how from some angles the rock appeared to defy gravity even while on the truck.
"It seems that "levitated mass" began the moment they were able to lift the boulder off the ground," she said. "It was levitating above the streets as it traveled. It was something to see."
The project, anticipated to cost as much as $10 million, is being funded by well-heeled museum donors.
With the rock finally in place, museum officials hope it will be ready to be unveiled sometime in the late spring or early summer.
