Wind-Whipped Wildfires Bear Down On Yosemite National Park

Winds from a thunderstorm pushed a blaze near Yosemite National Park farther into a grove of 2,700 year-old giant sequoias.

Fire information officer says crews don't know yet whether the 15-square-mile fire has damaged any trees in Nelder Grove outside the park. She says giant sequoias are resilient and can withstand low intensity fires.

A thunderstorm over the blaze pushed it out about a mile in a span of two hours. The fire is partially contained and has forced the evacuation of a small town. The Nelder Grove holds more than 100 giant sequoias, including one of the world's largest, the 24-story-high Bull Buck sequoia.
