Santa Barbara County firefighters this morning are mopping up at the scene of a brush fire which caused a big scare.
The fire was discovered just after 4 p.m. near the Harris Grade summit, northeast of Lompoc. It put up a massive cloud of smoke visible for miles. Firefighters aided by eight air tankers, and two helicopters quickly responded to the scene, and had the fire more than 40% contained by sunset last night. It was estimated to be 10 to 20 acres in size, with firefighters expecting to get a more accurate estimate today.
No structures were threatened by the blaze, which burned in pine trees on the east side of Harris Grade. Investigators believed a spark from the catalytic converter of a passing vehicle started the fire.
