'Apocalyptic' Scene as Sierra Nevada Mountains Cloaked in Smoke From Caldor Fire

Air quality alerts were issued to California and Nevada residents living near the Caldor Fire, which by August 25 had burned more than 197 square miles, officials said.

Caspar Donnison shared footage he captured from aboard an Amtrak train traveling through the Sierra Nevada mountains in California on August 23, calling the scene “apocalyptic.”

The National Weather Service said the Reno/Sparks area of Nevada recorded its worst-ever air quality as smoke from the nearby Caldor Fire suffocated the region.

“For those of you wondering if the air quality yesterday was the worst ever in the Reno/Sparks area … the answer is an unfortunate yes,” the weather service said on Twitter August 23.

As of August 25, officials said the fire was 126,182 acres (197.1 square miles) in size and was 11 percent contained. More than 2,600 personnel were on the scene fighting the fire, which started on August 14, according to official reports. Credit: Caspar Donnison via Storyful
