Ozone pollution has worsened at some national parks posing health risks to visitors but also leading to improved visibility.
"Ozone is a colorless, odorless pollutant, making it possible for visibility to improve sharply in Yellowstone National Park, for instance, even as ozone levels climb steadily. Brown haze and other visible smog has decreased in many parks because of a 1999 Environmental Protection Agency edict...which has led to stiffer controls on industries that produce visible particulate pollution.
...huge increases in oil and gas drilling in interior western states â€" along with emissions from coal-fired power plants, cars and other sources â€" were causing ozone to drift across some of the nation's most famous parks."
