Firefighters attempt to save giant sequoias as Yosemite wildfire grows

From Friday to Sunday, the blaze expanded from 250 acres to roughly 1,600 acres as over 400 firefighters have tried to contain it

A grove containing some of the world's oldest giant sequoia trees is under threat from a rapidly growing wildfire at California's Yosemite national park.

From Friday to Monday, the blaze expanded from 250 acres to roughly 2,340 acres, with the terrain of timber and brush fueling the flames, officials said. Visitors on the Washburn trail of the Mariposa Grove of Giant Sequoias first reported the blaze on 7 July, and 545 firefighters and other personnel were currently working to contain it as of Monday.
