    They are still burning coal in power plants in that neck of the woods…and when the weather gets bad and visability is poor, they burn the worst of it so that the visable yellow gray smoke wont be seen. If you watch a plant over time and note the type of weather present you can see a difference.

    Ralph – How would you compare Idaho Falls? I felt sick when I drove down from Teton into Idaho Falls along the Palisades Reservoir last summer. The air reminded me of Chicago.

      Northern Utah in the winter is much worse than Idaho, although all the mountain valleys can trap pollution in an inversion.

      Summertime air pollution in Idaho, outside of the Boise area where there is a lot of traffic air pollution, is primarily from forest fires. Southern Idaho also gets dust storms that blow off of denuded and desert lands.

      I don’t know what would make you sick where you were. That is a clean air area except during some forest fire years.
