If the right conditions persist a prescribed burn will take place on the Mt. Adams Ranger District this Wednesday through Sunday.  The prescribed burn site is located about six miles north of Trout Lake and four miles south of the Mt. Adams Wilderness area within the Upper White Restoration Area.  District officials say it may be necessary to temporarily hold traffic on Forest Roads 8020, 8225, and 021 due to limited visibility caused by smoke and to keep the public at a safe distance from the burn areas.  Smoke may be detected in the towns of Glenwood and/or Trout Lake but is not expected to travel further.  There will be visible smoke in the area for several days following the burn.  The Upper White Salmon Restoration prescribed fire project calls for understory burning of 1,712 acres of the Upper White Restoration Area with the intent of creating a landscape more resistant and resilient to wildfire, insects, and disease.  This burn will focus on the completion of a 288-acre portion of the project area.  The other three units will be burned over the course of the next several years.
