The Yosemite fire grew to more than 200 square miles Sunday, threatening two groves of giant sequoias as well as the Hetch Hetchy Reservoir supplying water and power to San Francisco, consuming some two dozen structures and threatening 4,500 more.
What’s called the Rim Fire is just 7 percent contained. And while its spread slowed somewhat Sunday, it continued to grow.
"This fire has continued to pose every challenge that there can be on a fire: inaccessible terrain, strong winds, dry conditions,” said Daniel Berlant, spokesman for the California Department of Forestry and Fire Protection. “It's a very difficult firefight.”
High winds are making that firefight even more challenging as ground-level blazes whip up to treetops, creating what are called crown fires.
"A crown fire is much more difficult to fight," said Mr. Berlant. "Our firefighters are on the ground having to spray up."
