My friend left me alone. Can anybody answer me, what should i do.


Wow. You've made me almost not depressed about having to go back to Utah for a week this summer. And that is saying a -lot- to your credit.

Hang in there! Perhaps I'll post about summer physics in Utah as well. I'll take a week in Utah over a week in my family reunion destination in the corn fields of Iowa any day.

Nice article! I work up at the University of Utah and live in the upper avenues so the dirt air is always right at eye level.

And I'll take Utah in summer any day over winter in the valley, at least. This air just grosses me out.

Inversion is the main issue with bad air in LA, if memory serves. (I grew up in Pasadena.) It may be urban legend, but I remember hearing that there was smog in the basin, from inversion trapping Native American cookfires, when the Spanish arrived.

Those of us who lived through the London Smog of the Fifties know about inversions..and what happens if you burn large quantities of coal underneath them! There were so many deaths that the figures were'nt released until years is now thought that 12,000 perished. Comparable with the London Blitz from Sept. to Nov. 1940 when 12,696 is the official death toll. I can remember bus services running with the conductor walking in front shining a torch on the side of the road and the driver following his instructions...
Later on, learning to fly in the RAF, I recall climbing up through the inversion and looking down froom the crystal air at the muck we were all breathing on the surface, and regretting having to go back down there...

A one month inversion is pretty crappy but I'm guessing you didn't live in this valley here in the early 1980's. Starting in the early part of December 1980 and carrying through to the end of February 1981 we had an inversion lasting nearly 90 days. Good thing for night skiing.

Apparently the inversion phenomenon has affected people, more harshly than I realized. It's certainly not limited to Utah. Brad, I was not in the Salt Lake valley in 80-81, so I guess I dodged that bullet, but, we could reasonably have such an occurrence again. It looks like health issues (esp the example about London in the 50's - thanks John) are just one more reason to push for non-CO2 emitting energy sources. Salt Lake City is finally catching up with the rest of the world and has vastly improved their public transportation systems in the past 10 years, so that's one step in the right direction.

Hi! I just found your blog thing. Used to be in UT, hated the air. Hung out in the mountains as much as I could to avoid breathing it. :) Geography really does make a huge difference. Now that I'm in AK, we get inversions all the time. Cramped, narrow valleys are the last to have their inversion layers disrupted, because they're so sheltered. So it's the gorgeous mountains in SLC that are ruining you all's lungs. :)

Love the post!

Great blog. We too, in the Okanagan Valley in beautiful British Columbia, experience inversions (see to see where we are). Some last a week, some last longer.

Thankfully, it's relatively easy to escape the gloom. A 30 min drive will put you above the clouds and into the beautiful sunshine.

I have a cure for SLC smog.. the clean fresh air of the lower Bay Area! ;)

How do you reconcile loving your home city so much (Los Angeles) and bemoaning its obvious detriment to your health?

Personally, I don't try to reconcile it! Inversions are part of nature, and are part of the eco balance so I can't blame them. Rather, I push every day, in my own little way, for alternatives to fossil fuels so that one day we can forget smog ever existed.

I guess living in a polluted city is like eating's a sacrifice we make for other benefits.

Just try to guess...
I think nissan is good.

Those are some great photos, I'd love to just hike around that area.

very nice post!!!


Inversion layers (or something quite like them) also cause the Tule fog in the California Central Valley. Which is impressive, considering the sheer size of the valley.
