A massive wildfire in Mariposa County triggered a new round of evacuations Tuesday as flames threatened power lines that feed Yosemite National Park, officials said. By noon Tuesday, the Mariposa County Sheriff’s Office extended evacuation orders to residents in the town area of Mariposa, east of Merced. Along the southern flank of the blaze, flames threatened power lines that supply Yosemite National Park, Cal Fire said. Farther west, firefighting efforts in Saratoga were hampered Monday night by an unexpected drone sighting, said Ryan Cronin, chief fire investigator for Santa Clara County Fire Department. The drone was spotted about 7:40 p.m. as a water-dropping helicopter from Cal Fire prepared to douse the area, he said.
