The Bull Fire is now 96% contained.
The fire broke out last week and burned more than 16,000 acres, along with eight homes and six outbuildings.
Over 450 firefighters remain on scene.
They now expect to have the fire 100% contained by next Tuesday.
But fire investigators are still looking for the person or persons who started the fire.
