michael heizer is an american contemporary artist started creating large-scale sculptures and land art in the late 1960s. 

in 2006, he ran into a giant piece of rock (340 tons) at a stone valley quarry in riverside county california. 

the transportation of the boulder to lacma took 11 days and the cost of the whole project reached up to $10 million. 

the huge vehicle carrying the boulder passed four counties and 22 cities—trees were cut down, cars were towed and some of the traffic lights were removed to help the transporter move. 

hundreds of people were waiting to see the installation arriving and the journey took more attention than the artwork itself.

heizer never gave a public speech about his work but he emphasized the importance of the size and its longevity which is meant to last about 3.500 years.
