Pollution Smothers Salt Lake Valley (IMAGE) University of Utah Caption The Salt Lake Valley is socked in by a thick inversion of polluted air, as seen from one of the canyons in the Wasatch Range east of Salt Lake City. The Oquirrh Mountains rise in the distance. Better understanding such inversions is the focus of a three-year, $1.3-million study funded by the National Science Foundation and led by the University of Utah Department of Atmospheric Sciences.
