The Barlow Ranger District plans to implement a series of prescribed burns west of Wamic over the next several weeks.  Depending on the weather, fire personnel may start ignitions as early as Friday on the North and South Rock prescribed fire units.  Both units are located approximately 3 miles SW of Pine Hollow and 5 miles west of Wamic.  The two areas are about 622 acres combined.  Fire personnel are planning for up to three days of ignitions.  Visibility along Mt. Hood National Forest roads in the area and nearby Rock Creek Road may be temporarily reduced.  Smoke may also be visible from Highway 197.  No road closures are anticipated, however access to Forest roads in the burn perimeter may be temporarily restricted while firefighters are actively lighting.  Forest visitors traveling in the vicinity should use caution and adhere to any closures to provide for firefighter and public safety.
