Given that the College itself is only a few centuries old, this method would be a crapshoot at best. Still, a custodian organization like the Undergraduate Council, with a track record of periodically losing and re-discovering things, might insure that the capsule remain undisturbed.
Finally, a few suggested that we put the thing into an object that the campus will hold as semi-sacred. This could be the base of the John Harvard statue, the tower of Memorial Hall or a metal mold resembling the Eudocimus albus (the North American ibis).
The upshot of all this is that a Harvard millennial capsule is probably a really bad idea. But that probably won't stop somebody from trying.
