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.

Yeah this quiz would be a lot better if it included Canadian cities. Still, as a non-American, this type of quiz (area of the U.S. on a map, name the cities) is one of my favourite, and this specific one was a great idea.

If this thing ever blows it's going to be bad for Bangkok and Sydney, too, and all the cities inbetween.

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

Aug 28, 2020
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.

@Jerry - on a large (continental) scale, we have a pretty good idea. Global Circulations are well known and while they do vary, the underlying patterns are pretty reliable.

For anyone interested, there's tons of info at www.noaa.gov and www.weather.gov

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.

Maybe link to the Wikipedia page you got data from? I was baffled by these numbers until I found it: https://en.wikipedia.org/wiki/Metropolitan_statistical_area. Grew up in CO and have never considered Greeley a 'metro area.'
