haze, skyline, Salt Lake City, Utah. 霧霾, 天際線

In this Wednesday, December 28, 2016 photo, the downtown skyline of Salt Lake City, Utah is shrouded in haze during an inversion. In the phenomenon, cold, stagnant air settles in the bowl-shaped mountain basins, trapping tailpipe and other emissions, creating a murky haze that engulfs the metro area. (Photo by Jeffrey D.
