On the road with LACMA's big rock, minute by minute After months of delays, a massive rock heading to the Los Angeles County Museum of Art got underway Tuesday night. The 340-ton granite boulder and its caravan are weaving their way from a quarry in Riverside to the midtown museum. The 105-mile journey is expected to take 11 days -- nights actually, as the traveling will be done between 10 p.m. and 5 a.m. MAP: Follow the route The giant boulder eventually will be the focal point of artist Michael Heizer's landmark sculpture, "Levitated Mass," on the grounds of LACMA. During the first leg, the caravan traveled 4 to 5 mph, with dozens of workers from Emmert International, the company handling transportation of the boulder, traveling on foot behind the rock. It has stopped for the day in the town of Glen Avon. Joining the first leg was Los Angeles Times reporter Deborah Vankin, who live-tweeted from the scene until early Wednesday. Here, for those who were not following in the middle of the night, is a recap of her tweets and photos.
