Crews “made good headway” against the Oak Fire, according to a Sunday night incident report by the California Department of Forestry and Fire Protection, or Cal Fire. “Fire activity was not as extreme as it has been in previous days.”

But smoke from the fire drifted more than 200 miles (322 kilometers), reaching Lake Tahoe, parts of Nevada and the San Francisco Bay Area, officials said.

“It’s been just horrendous with the air quality,” said Kim Zagaris, an advisor with the Western Fire Chiefs Association, which maps wildfires across the country.

More than 2,500 firefighters with aircraft support were battling the blaze that erupted last Friday southwest of the park, near the town of Midpines in Mariposa County. Officials described “explosive fire behavior” on Saturday as flames made runs through bone-dry vegetation caused by the worst drought in decades.
