Firefighters are gaining ground on the blaze threatening an ancient grove of giant sequoias in Yosemite National Park.

Crews started clearing dead trees and brush out of the historic Mariposa Grove and began building a line around the nearby town of Wawona, California, to hold back the flames, according to Matt Ahearn, an operations section chief battling the blaze. The few hundred residents of Wawona were evacuated earlier.
