LOS ANGELES (CBS) — The “Levitated Mass” exhibit featuring a 340-ton granite boulder is expected to open to the public this Sunday at the Los Angeles County Museum of Art (LACMA).

The sizable boulder’s journey from a rock quarry in Riverside to Los Angeles was a slow and steady journey over a span of 11 days.

On March 10, the rock finally arrived at LACMA  and has since been transformed into a floating art display.

Michael Heizer, the artist behind the exhibit, first conceived of the idea in 1968, but only discovered the right boulder decades later.

Museum admission will be free until July 1 for those living along the rock’s transport path.
