Wildfire near Yosemite forces thousands to flee homes

(CNN, July 19,2017): About 4,000 people have been evacuated, including the entire city of Mariposa a few miles west of the Yosemite National  Park, and eight structures have been destroyed, officials said. The park itself has issued no warning for visitors, but the fire is threatening power lines that supply Yosemite, state fire officials said. Gov. Jerry Brown declared an emergency for the county.
