Have no fear, folks. The eruption of Yellowstone would be an extinction level event for humans, regardless of where they lived.

After the last few years, I’m honestly thinking that might not be such a bad idea. We had a good run (for some definitions of “good” anyway). I say we wrap it up and call it a civilization.

Amazing quiz! Just out of curiosity, why does the ash appear to spread farther to the east than to the west?

I guess that's because there are mountains (Rocky) to the west and great plains to the east.

Probably that and a mix of wind speed and direction.

Yeah, if it was not the capital of Missouri, Jefferson City would be pretty insignificant.

Columbia is a city with a big university and medical centers. Jeff City just has state politics and a prison, and MO spends as little as possible on state politics. Years ago I was helping plan a young farm women's conference and was surprised to see that the head of the state secondary education department had a tiny cubicle in a large room with other department heads. Then I met with a professor at Mizzou in Columbia and she had a large, carpeted office with two secretaries in outer offices. I mentioned the large difference to the state head and he said that's state funding versus federal. He said people in his department bring their own brown bag lunches, too, while those at the land grant university had expense accounts.

It is, the dots represent population not the literal area of the city.
