               Beaverhead County, Mont., November 1st, 2020 — Fire crews continue conducting burnout operations and securing the perimeter today on the Sourdough Fire, which is now 75 percent contained and approximately 5,811 acres.  Decrease in acreage is due to accurate mapping.

             Including the Sourdough Fire, Beaverhead-Deerlodge National Forest (BDNF) fire personnel and dispatchers are responding to five fires within the forest currently. A recent change in weather has quickly diminished any beneficial moisture from recent snowfall.  Varying wind speed and direction, along with an increase in activity due to the opening of rifle season just over a week ago, are all factors affecting the current fire situation.

            Many BDNF fire crews recently arrived back from assisting fire fighting efforts throughout the nation and are now working hard on fire suppression and containment efforts in several places within the forest as we enter November. Earlier last week, many BDNF personnel reported finding abandoned, active campfires and BDNF is asking the public to be especially conscious of making sure campfires are completely extinguished as they enjoy public lands.

            No structures are currently threatened, and no closures are in place at this time. Local landowners have been instrumental in supporting fire crews and facilitating a rapid response to mitigate potential threats and assist Beaverhead-Deerlodge National Forest personnel. The cause of the fire is under investigation.

            For further information and questions, please contact the Dillon Ranger District at (406) 683-3900.
