March 31, 1958 – Grand Canyon Diorama is Added in Disneyland
On March 31, 1958, the grand opening ceremony of the Grand Canyon Diorama, the “largest diorama in the world,” was held in Disneyland Park. The diorama was placed along the route of the Disneyland Railroad, and Walt Disney himself was the conductor of the train that passed by the scenes of the Grand Canyon. The soundtrack for the scenery is Ferde Grofé’s “Grand Canyon Suite,” which accompanies lush scenes of the landscape by scenic artist Delmer Yoakum. The diorama is 306 feet in length, and was restored in 2017 to how it would have appeared in 1958, with some subtle updates to add some “magic.”
