Francisco Kjolseth | The Salt Lake Tribune Utah is currently experiencing the worst summer air quality in nearly ten years, largely due to a persistent high pressure system that has parked over the Wasatch Front. The summer equivalent of an inversion is not as obvious to spot but the high ozone levels are there none the less as seen near the Salt Lake Valley on Tuesday, Aug. 1, 2017.
