Greetings from Gunkville



Salt Lake City makes the Associated Press top news stories list... for being dangerously polluted.

Northern Utah's valleys have been smothered by an "inversion," a blanket of warm air that keeps cold air close to the ground and traps everything: car exhaust, factory emissions, even hard-to-see particles from furnaces or a cozy fireplace.

Together they form a cloudy shroud that has been described as soup, gunk, smog, and a few other titles that can't be printed.

Who knew? There's a whole terror-alert style color code for air quality.
