PRINEVILLE, OR -- Ochoco National Forest Fire managers plan to burn piles left over from thinning projects in several units this fall, as weather conditions allow. Plans call for ignitions of 200 to 300 acres in the McKay area northeast of Prineville beginning  today and continuing through Thursday. These burns include around 3,200 acres of treatments scheduled this fall south of McKay Creek in the Green Mountain vicinity. Light smoke will be visible from Prineville and may impact dispersed camping sites. No burning is planned Saturday or Sunday, September 28th and 29th, because it is the opening weekend for mule deer rifle hunting season.
