Tulsa, Oklahoma: Time Capsule: 1998 Car Buried Here

Ten years before the 1957 Belvedere from Oklahoma's fiftieth anniversary was dug up (and it was discovered that they put the gunite inside the time capsule when it needed to be on the outside to keep the water out) Tulsa had its hundredth anniversary. The city decided it would be cool to bury another Plymouth to be dug up later. They selected a Prowler, bought it, and, being slightly smarter than the politicians of 1957, enclosed it in an aluminum case before burying it in the old Central Park (which was renamed Centennial Park at that time). In 2007, when the condition of the poor Belvedere became known, it was decided to exhume the Prowler and re-bury it above ground. The large mound can be seen near the corner of 6th and Owasso.

The Time Capsule burial vault is covered with slabs of concrete. It's interesting to read about if you're in the area.

Can't wait until 2048.

A centennial time capsule, interred on Jan. 17, 1998, in honor of the City's 100th birthday, is buried at Centennial Park. The time capsule, scheduled to be unearthed in the year 2048, includes items such as a prototype of the 1998 Plymouth Prowler, a City of Tulsa Financial Report, student essays on what Tulsa will be like in the year 2048, and Tulsa restaurant menus.
