The 100 and 1,000 year capsules are still scheduled to open in 2068 and 2968, respectively. Among the items stored in the monument is a passbook to a bank account containing a $10 deposit made in 1968, preserved within the 1,000 year time capsule. The monument also serves as a sun dial, its features oriented to the Sun to tell the time.
