Hi Michele,

What gets me getting further into the movie about it, is how huge it is. I didn't realize either it was a valconoe. I may have read somewhere once but have long since forgotten. When the scientist put it into perspective comparing the blocks, that was eye-opening. But when the USGS guy showed the reporter just how big it actually is standing by lake Yellowstone, now that is mind-blowing. Learning, and seeing, how deadly those pyroclastic flows can be really drove it home for me. Not only how they can sear a person instantly but how far a range they can damage the land. So even if one escaped the immediate damage of an eruption, the long term effects on air and food supply would, as you say, end life as we know it for sure. I hope by then I'm ready to let go.

All the best, Barb
