This satellite imagery, posted Wednesday, July 19, 2017 on a National Oceanic and Atmospheric Administration website, shows a large plume of smoke spreading hundreds of miles east from the Ditwiler fire, near Yosemite National Park in California’s Sierra Nevada. Authorities say the stubborn wildfire burning in foothills west of Yosemite had destroyed dozens of structures while forcing thousands of people from their homes Wednesday.
