A full-on assault is under way on a fire in Yosemite National Park that started out to be a prescribed burn of 90 acres but now has charred more than 2,200 acres.
The Big Meadow Fire was set Wednesday on the southwestern edge of the park but it quickly jumped the designated perimeter lines. More than 500 firefighters, backed by three helicopters, four air tankers, and 24 engines are battling the flames.
The fire has forced the closure of the Big Oak Flat Road (Highway 120) from Crane Flat to the junction of the El Portal Road (Highway 140). While no homes have been lost, residents of Foresta and campers in the Crane Flat Campground were moved and there continues to be no access to these areas. Highway 120 in the park will remain closed until further notice.
The fire is currently 10% contained.
