The annual Willard Springs green waste burn will take place today south of Flagstaff. Members of the Coconino Public Works Department and the Coconino National Forest will conduct the burn at the Willard Springs Transfer Station 17 miles south of Flagstaff. The burn will consist of getting rid of pine needles and tree trimmings. The burn will last until the spring and could produce heavy smoke over the next three weeks. Smoke will likely be seen from Interstate-17 in the area.
