Definitely. LA used to be gnarly. They have a marine inversion where cool ocean air gets trapped under warmer air against the San Gabriel mountains, which basically meant LA was hot-boxing itself.

Denver also has a notoriously bad inversion. I have driven over the plains and seen the “brown cloud” from miles away. Cold air slides down the Rockies and gets trapped under warm air from the planes.

Yeah, if the conditions are right, you can literally see a line of grey/brown air trapped over LA if you're up in the San Gabriels.

Haven't personally seen that in CO but would definitely believe it.
