[Rockhounds] Something going on in Yellowstone

[Dora Smith]

Done.  I added it to my web page.

But you might want to take al ook at it.   Because the situation is more 
complex.  One thing I added is a paper that discusses teh full geological 
complexity of the region, and the maps make it pretty clear as well that teh 
basalt traps and the hot spot are separate processes.   They just happen to 
have both crossed overlapping parts of the Snake River plain.  The flood 
basalt was born of some rifting process.
