Alder Creek Fire: 
Fire growth that was observed yesterday was primarily isolated to the Foolhen Ridge and pockets of unburned fuel. No new fire growth occurred outside of containment or contingency lines. Unmanned Aircraft Systems were used for aerial scouting around Bryant Creek. Crews will work on contingency lines along the northwest side of the fire near Bryant Creek. Air resources will focus their efforts in active areas, likely between Stine Creek and Deno Creek. The goal will be to moderate fire intensity and slow progression.

Christensen Fire: Yesterday Engine modules and Skidgines worked together hot spotting on the northwest side of the fire, near Toomey Creek. Resources will continue to secure and check-up fire in that area. Firefighters will patrol and monitor the Trident Peak area in anticipation of the fire moving towards the Sawlog drainage. Work will continue improving contingency lines.

Trail Creek Fire: Heat remains on the Northeast side of the fire near Big Hole Battlefield and on the southwest side near Three Mile Creek. Unmanned Aircraft Systems were used for scouting around Three Mile Creek. This area continues to be a focal point; however, the fire remains east of the drainage and crews will monitor for continued activity. Green islands in the interior of the fire continue to produce smoke, as unburned fuels are consumed.  Containment lines have been completed or near completion in the areas of Hirschy Ranch, Gibbonsville road, and Anderson Ridge. Chippers will be utilized to clean up excess unburned fuels, and resources are prepared to execute contingency plans should the fire reach management action points.

Black Mountain Fire: No additional fire activity has been reported. Contingency lines are complete should the situation change. Firefighters will use three chippers to clean up excess debris produced from road improvement and will patrol and monitor the area.

Fire Weather Today: Today’s temperatures will be in the low to mid 80s with minimum relative humidity in mid to high teens, and West-Northwest winds at 8 to 10 mph with gusts of 15 to 20mph. Winds are expected to be minimal and predominantly terrain driven.
