CALIFORNIA -- Crews are still struggling to get a handle on the large fire burning north of Foresthill. It's only 5 percent contained.

Yesterday the fire was at about 1,900 acres, while today it has grown to 3,050 acres, according to Marc Brown, a Tahoe National Forest Spokesman.

Brown says the American Fire is posing quite a challenge because of very steep and rugged terrain. More than 500 personnel are now on hand, trying to get lines around the new growth.

The fire is primarily growing toward the north, along Deadwood Ridge, Brown said.

Six helicopters are available and a DC-10 airplane was used yesterday. Air quality is still a major concern, heavy smoke will remain in Grass Valley and along the Highway 80 corridor in Auburn and Colfax.
