SUNOL (CBS / AP) — Fire officials said a brush fire burning in an unincorporated area of Alameda County has been contained.
CalFire Battalion Chief Jim Crawford had said the fire consumed about 300 acres but after using GPS mapping devices, crews determined the fire burned only 60 acres.
Earlier on Friday more than 200 firefighters and three helicopters were battling the blaze, Crawford said.
The fire spread quickly through a rugged grasslands area shortly after it broke out, Crawford said.
Multiple agencies responded to the blaze Friday afternoon, including Alameda County, East Bay Regional Parks, Fremont and Livermore-Pleasanton fire departments.
No structures were threatened by the blaze. The cause of the fire is under investigation.
