The Flat Fire has burned 156 acres and is 32-percent contained. The fire is burning on the north side of the San Francisco Peaks, about four-and-a-half miles west of Highway 89. The fire has burned through pinyon-juniper and grass. Fire investigators say the fire was started from a private citizen burning grass trimmings in a burn pit that got out of control due to wind conditions and spread quickly.  The Coconino County Sheriff’s Office arrested an individual and charged him with reckless burning and violation of the county fire ban.
