The more people move here, the more smog there is going to be. Plain and simple. Montana's quality of living is going down with the influx of people moving in. To some it's better than where they came from, but to those of us who have been here a long time its the opposite. I guess there is good and bad in everything.

Just like the eagles song, "Call someplace paradise, kiss it goodbye."

I've been curious about this myself. We're always told its from the fires but we have smog sometimes when there no fires anywhere in the west. I don't know what to tell you but I hope someone comes on who can because I would like to know myself.

We get that "haze" all the time here in the west valley. I was told it is pollution... from what I have no idea but you can't deny the haze is here ! Most prevalent during the morning and evening sun.

Natural dust (particulates) is now considered "pollution". Natural dust plus fog off the river equals smog if you're only counting particulates. So you can see that it's not useful to call it "smog" unless you know what the composition is.

During the winter months, cold air gets trapped in the valley, below 5000'. This sets up a smog/haze condition, and this can go on for several days to weeks. In fact, while Great Falls might be up around 50 with chinook winds, Helena might be hovering around 15 degrees, with no wind. For people with respiratory issues, this can be a problem. It usually takes a good front to knock out this air inversion (a winter time phenomenon where the colder air is at a lower elevation than the warmer air).

Hope that helps!

We're talking about the summer/spring smog. Its not from the fires either... There's just a strange smog that fills the air even when California fires are not big yet...

Actually, the op did not specify a season. They just asked if smog gets trapped in the valley, and I answered the question.

Thanks for answering the question friend from Texas, but I live here and I see the smog in various seasons. Everyone knows about inversion, this is something different.
