- Aerial view of NE Salt lake near the University of Utah during the Dec 5, 2010 inversion event. by Tim Brown
This series of panoramas was taken above Salt Lake City during a "red air" inversion day. During inversion events like this, a layer of high warm air traps cold air into the valley. The fog and clouds mix with the high levels of pollution to create unhealth, toxic air pollution levels in the valley.
