I think the 2000 year cycle is off by a couple of digits. Otherwise, one would have happened at the time of Christ and there is no mention of it in historical records.
According to the Yellowstone site, that one erupts about every 600k years and is 40k years over due http://www.solcomhouse.com/yellowstone.htm
Fascinating theory tho. As Earthquakes increase in quantity and magnitude preceeding a volcanic eruption, we may know more soon enough.
I had not heard of any, and indeed the site I linked to really only talked about one relatively minor earthquake 9 years ago. COurse they say that Old Faithful is a result of the magma, so if he gets irregular, watch out!
No, they closed it to snow mobiles under Clinton, but Bush re-opened it for them. And as far as the deer, since they just re-introduced wolves there (after about a 100 year absense) that would not surprise me.
p.s. The plural of deer is deer. And you can get me back anytime as I am a terrible speller!
