LA museum to receive 340-ton boulder for art exhibit

The Los Angeles County Museum of Art (LACMA) has spent months trying to transport an enormous rock from a quarry in Riverside to the L.A. museum.

LACMA has invested millions of dollars in an attempt to move this 340-ton boulder, which because of its size and weight, will travel a slow, complicated journey that could take 10 days or more.

When it arrives at the museum, the rock will become the centerpiece of "Levitated Mass," earth artist Michael Heizer's latest creation.

The two-story chunk of granite will appear to hover over people as they walk underneath it.
