About This Lesson
On February 28th, 2012, the Los Angeles County Museum of Art began transport of a 340-ton granite megalith from a quarry in Riverside County to the museum's campus for the making of Levitated Mass, a sculpture by artist Michael Heizer. The eventual work wlll be composed of a 456-foot-long slot over which the megalith will be suspended. Heizer conceived of the artwork in 1968, but discovered an appropriate boulder only decades later, in Riverside County, California. At 340 tons, the boulder is one of the largest megaliths moved since ancient times.
