The Trinity Ridge Fire is increasingly slowing, cooling and diminishing in intensity.
Along the western flank of the fire, crews are continuing to prepare the Middle Fork Road for the fire’s approach. Helicopters are being used to slow the fire’s movement toward the Middle Fork of the Boise River. Hotshot crews have completed firelines in the Pete, Repeat, Big Five and Sheep Creek drainages and are shifting their work to securing the fire edge and mopping up.
On the northern side, fire activity in West Warrior Peak is being patrolled and monitored by air. Crews are also using brush-shredding equipment to finish a contingency fireline from Thorn Creek Butte to Rabbit Creek Summit.
In the southern quadrant of the fire, crews have secured the flank and are now mopping up and monitoring the fire. Helicopters will continue to cool hotspots in isolated areas where the fire skipped pockets of fuel. Overall, the southern and eastern flanks of the fire are looking increasingly secure.
Weather conditions today are expected to continue to be warm and dry over the fire area. Winds today are going to be calmer after the passage of yesterday’s front.
The Alaska Type 1 incident management team will hold a community meeting in Idaho City at the Basin Elementary School on Friday, September 7 at 5:00 p.m. Today’s community meeting in Pine will be the final scheduled informational meeting for the Pine and Featherville areas.
