Why the Court of Angels in New Orleans Square Matters

This is a little bit from The Disneyland Story: An Unofficial Guide
Another addition to Frontierland was not so obvious. One of the things Walt loved to do was to add little surprises throughout the park that guests could stumble upon. They were known as interstitials, events between the major events. One example was the petrified tree in Frontierland.

In July 1956, Walt and Lillian had driven through Colorado, near Pike’s Peak, just outside of Colorado Springs. Walt saw a “Petrified Trees for Sale” at Pike’s Petrified Forest. He pulled in and told Lillian to wait in the car. She was not happy with the detour and was starting to get agitated. When her husband returned, he proudly proclaimed that he had just bought her anniversary present; a petrified tree stump. The 5-ton stump was still in Colorado on their 31st anniversary on July 13, 1956. When she said that it was too big for the mantle, Walt brought it down to Disneyland. On Walt and Lillian’s 32nd anniversary, July 13, 1957, the 10-foot tree stump was installed next to the Rivers of America.
