FLAGSTAFF, Ariz. -- The Slide Fire burning in and around Oak Creek Canyon in northern Arizona continues to grow in size even though firefighters have established a containment line around all of it.
The fire's size increased from 28.9 square miles Monday evening to 31.7 square miles Tuesday morning due to burnout operations intended to deprive the fire of fuel.
The fire's official containment figure remains at 35 percent because some areas within the containment line still have active low-intensity fire while others remain hot to the touch.
The number of firefighters and other personnel assigned to the fire is now below 1,100, down from more than 1,200.
Fire management spokeswoman Jan Bardwell says some crews are being reassigned because there's less work to do.
The human-caused fire started May 20.
