Firefighters backburn to contain Yosemite wildfire

STORY: About four days after a wildfire started at the park, firefighters in California have begun to contain the blaze, which has threatened some of the oldest giant sequoia trees in the world, officials said on Monday.

None of the park's landmark giant sequoias, the world's largest tree species by mass, have been reported destroyed by the fire, officials said.

The fire has burned 2,044 acres (827 hectares), officials reported.

The park's Mariposa Grove, home to over 500 giant sequoias, has been closed since Friday. The community of Wawona - which is located in the park and includes Wawona Hotel and a campground - was evacuated. The rest of the park remains open.
