Forest service crews conducted another round of pile burns in and around Flagstaff Monday. Burns sent smoke into the air from fires set just north of the city, along the southwest base of Mt. Elden and south of Elden Lookout Road. Coconino National Forest officials say the burns are part of phase one of the Flagstaff Watershed Protection Project and will continue this week. Crews will also be burning along Highway 180 and Forest Road in the Fort Valley Area. Piles will also be burned on the south end of the forest near Clints Well this week. Smoke from the burns near Flagstaff will be seen from the city and surrounding areas.
