Gifford Pinchot National Forest fire managers will conduct prescribed burning south of Mt. Adams starting as early as October 7, and continue through Oct. 21, if the right conditions persist.  The prescribed burn site is located about six miles north of Trout Lake and four miles south of the Mt. Adams Wilderness area that was planned as part of the Upper White Salmon River Restoration Project.  Gifford Pinchot National Forest South Zone Fire Management Officer Loretta Duke says shorter days, elevated relative humidity, and recent rainfall in the prescribed burn area have helped create suitable prescribed burning conditions.  The Upper White prescribed fire project calls for understory burning of 1,712 acres with the intent of creating a landscape more resistant and resilient to wildfire, insects, and disease.  This season, the focus will be 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.  Prescribed fire signs will be posted at both ends of the project area to increase public awareness.  Smoke may be detected south of Mt. Adams in the towns of Glenwood and Trout Lake but is not expected to travel further.  There will be visible smoke in the area for several days following the burn.
