Overlooking the haze
Haze comes from such sources as water vapor, dust, and air pollution. Air pollution can come from locations many miles away. Southern California industrial plants, power plants, wood stoves, and automobiles belch soot, dust, and smoke into the atmosphere. Prevailing winds direct the air east and funnel it through Banning Pass, where it is dispersed throughout the Coachella Valley.
