On A Rock

Opening Day. Photo courtesy of LACMA.org.

Recently I spent an evening at LACMA.  One of the museum's many draws that evening (aside from live Jazz, catching up with a friend, and an opening exhibition) was a gigantic rock atop a concrete walkway.  I am sure many of you have heard of it-- Levitated Mass by Michael Heizer. The hoopla caused by bringing this celebrity rock to the Miracle Mile meant more to me than seeing the rock actually set in place.  The process of getting the rock to Los Angeles is better explained here and will soon be made into a documentary.  Will you watch it? A movie about a rock?  Some interesting deets about this rock:
The rock will remain where it currently is for the next 3,500 years. (Who came up with that number?)
Heizer once dug a series of holes in the Sierra Nevada and is currently working on a three square mile project called "City".  He has been working on "City" since 1970. 
He tried to build Levitated Mass with a smaller boulder back in 1962 and the crane snapped. 
This exhibition cost upwards of $10 M. 
So is a rock, just a rock, just a rock? or so much more?
You tell me.
