26. Levitated Mass by Michael Heizer, 1969-2012
Known colloquially as "the Rock," Michael Heizer's latest project wooed Southern California residents on its 105-mile journey from the Riverside rock quarry to LACMA. The closely-documented tow lasted almost two weeks, because it's top transport speed was recorded at five miles per hour. Despite its tedious haul, Heizer's boulder attracted followers, reception crowds at pit stops, and full newspaper spreads over the course of the installation. Its notoriety in recent news is only a testament to the social and art historical parallels that are exposed, as Angelenos now gather around a massive rock akin to an ancient megalithic monument.
