Photo by @Gerd Ludwig. Sunlight barely permeates the fog to illuminate this view near Clingman’s Dome. Dead Fraser Firs, the result of balsam woolly adelgid (aphids) infestation due to air pollution, are fast becoming a common part of the landscape.

The Great Smoky Mountains, aptly named for naturally occurring mist-like clouds that quite frequently surround the mountains, are affected by air pollution from nearby industry, power plants, and cars. The pollution appears as a uniform haze, which threatens the health of flora and fauna and degrades visibility. The National Park Service works with state agencies to observe nearby industries in order to minimize the amount of new pollution produced and carefully monitors the air quality in the park. Follow @Gerd Ludwig to see additional views of the Smokies I posted during the past few days. @thephotosociety @natgeocreative #mountains #pollution #landscape #GreatSmokyMountains #environment #haze #ClingmansDome #FraserFir #fog
