SEL,
This is a great little video for those of us who have not been to Yellowstone (yet). The scenes really "bring home" the volatile character of the
park. He suggests that the Yellowstone "hotspot" is the remnant of the of massive volcanic activity on Pangea which led to the Permian extinction
event (the largest in the history of the planet), 500 million years ago. He is the first person I have heard suggest that this ancient vulcanism was
due to a metorite impact - interesting. Out of curiosity I will try to find out if that portion of North America was once the area of Pangea which
underwent the massive eruptions.
Thanks.
