Not even smoky skies can keep hikers and climbers from enjoying America’s national parks, researchers found. The study’s lead author, Matt Clark, took this picture of a climbing partner in Yosemite. They drove six hours to reach the park and climbed despite high smoke levels. “I was kicking myself for days afterward,” Clark said. “My lungs were burning.”
