Mysterious Monolith Marks 2001, then Disappears
In what can be considered the first real "2001" mystery: A black, steel monolith nearly three meters high mysteriously appeared on a grassy knoll in Magnuson Park in Seattle on New Year's Eve. Then, almost as quickly as it appeared, the monolith disappeared Wednesday morning.
Some think that the mysterious placement of the monolith refers to the classic science fiction film 2001: A Space Odyssey.
The most obvious question: who is its creator? Sadly, there is no answer. The hollow structure had no plaque or identifying marks.
