Just saw a post on enenews about the Farallon Islands off the coast of San Francisco, and I mentioned it in another thread but it deserves it's own topic. The wiki is a good read, and I'm glad this is getting more attention.

Well, I guess it will occur in nature for a few thousand years more at least.
