The making of Cars Land mountains in Disneyland

Building Ornament Valley, the mountain range for Radiator Springs in Cars Land at California Adventure in Disneyland, took a team of artisans.

The range's peak is about 125 feet. At 280,000 square feet, this is the largest rock work job in any domestic Disney theme park – larger that the Matterhorn, Splash Mountain or, in Florida, Expedition Everest, according to Disney.

Here is a Disney video on the making of the mountains, with more than 4,000 tons of steel used.
