Salt Lake City Inversion (IMAGE) University of Utah Caption A wintertime inversion or "cold-air pool" traps air pollution over the Salt Lake Valley, almost completely obscuring downtown Salt Lake City in the center of the photo. The University of Utah campus sprawls in the foreground, on the city's east bench and mostly above the inversion. The University of Utah will lead a $1.3 million study aimed at better understanding conditions that lead to the formation, maintenance and breakup of the polluted inversions.
