Raging fire spreads in Yellowstone Park

FRESNO — A giant wildfire raging out of control spread into Yosemite National Park on Friday.

Authorities urged more evacuations in nearby communities where thousands have already been forced out by flames marching through the timbered slopes of the western Sierra Nevada.

The fire hit the park at the height of summer season, as officials geared up for a busy Labor Day weekend.

It has closed some backcountry hiking but was not threatening the Yosemite Valley region, one of California’s most popular tourist destinations.

The blaze has spread to more than 165 square miles and was only 2 percent contained.
