A multi-day prescribed burn in Deschutes County jumped containment lines on Thursday, prompting fire agencies to declare a wildfire. The fire on Pine Mountain, about 14 miles southeast of Bend, grew to 2,866 acres by Friday afternoon with the perimeter listed as 25% contained. The fire was mostly burning on federal land, as well as some private land. The wildfire declaration should help the U.S. Forest Service and local fire agencies tap into additional resources — like equipment and extra hands — as they dig containment lines around the fire’s perimeter. …That morning, the smoke appeared to be petering out, based on camera footage from the Oregon Hazards Lab’s wildfire camera networks. …On Thursday morning, the Forest Service announced it was canceling the burn “due to unfavorable conditions.” The agency declared the burn had turned into a wildfire that afternoon, after multiple spot fires appeared outside of the burn’s boundaries.
