PLYMOUTH -- Officials in Yosemite National Park say a relentless air assault helped limit the spread of a wildfire that has forced the evacuation of about 100 homes and sent smoke into Yosemite Valley.
Park spokesman Scott Gediman says the fire had burned through a little more than 4 square miles of brush and trees in the park, the neighboring Stanislaus National Forest and private land as of Monday morning.
It grew by about 500 acres overnight and was 5 percent contained.
The park is home to such sites as Half Dome mountain. It remains open, and none of its treasures is threatened.
Authorities evacuated an estimated 100 homes in Foresta and the small community of Old El Portal shortly after the fire began Saturday.
The blaze had quadrupled in size by Sunday morning.
