US wildfire gains strength, creeps into Yosemite
None
A wildfire raging along the northwest edge of California's Yosemite National Park gained strength Saturday, as officials cleared brush and set sprinklers to protect two groves of giant sequoias.
The iconic trees can resist fire, but dry conditions and heavy brush are forcing park officials to take extra precautions in the Tuolumne and Merced groves. About three dozen of the giant trees are affected. (AP)
