While on a tour of the American West, Walt Disney bought a petrified tree stump from Pike Petrified Forest in Colorado. For their 31st wedding anniversary, Walt presented the fossilized stump to his wife Lillian. Unsure of what to do with the unique gift, Lillian immediately donated the petrified tree to Disneyland, where it has been since 1956.

Pike Petrified Forest opened in 1920 as a commercial quarry (selling fossils), the tourist attraction featured a visitor's pavilion and ticket booth. Home to the famed trio of petrified redwoods, the private enterprise closed in 1961. On August 20, 1969, the site became a National Park, renamed the Florissant Fossil Beds National Monument.
