Michael Heizer, Levitated Mass, 2012. LACMA, Los Angeles.
a 340-tonne granite boulder placed on top of a 140-metre long concrete slot that opened to the public in late June. The Los Angeles County Museum of Art (LACMA) commissioned the piece, first conceived in 1969. Installed in a gravelly field just behind Renzo Piano’s Resnick Pavilion, visitors descend into the piece via the concrete slot that runs under the boulder and back up the other side: imagine two opposing handicap ramps shaded by a monolith. Levitated Mass doesn’t exactly levitate. On the recommendation of Buro Happold, two steel brackets and a dozen steel rods support the rock and keep it from rolling away in an earthquake.
