Upper elevations across the fire area are dominated by Aspen and timber fuel models with heavy dead and bug kill, with many patches of rock that help break up continuity. Lower elevations are dominated
by grass and sagebrush with timber stringers consisting of juniper and aspen.
There is active fire behavior northwest of the Moon Lake campground in Brown Duck Creek, in upper Rock Creek drainage, north of Dry Ridge, and in the head of Mackentire Draw. These areas are seeing rapid rates of spread and passive crown fire and short-range spotting. There is minimal fire activity along the lower portions of Rock Creek drainage with moderate intensity along the West Fork Rock Creek.
Utilize crews to hold critical line during forecasted arrival of cold front bringing 40 MPH winds on NE flank. This will protect critical infrastructure by preventing fire spread into Hells Canyon and Yellowstone Canyon. Crews will also continue mop-up on southern perimeter and patrols in Rock Creek drainage.
Projected Incident Activity:
Fire activity today will remain minimal until inversion lifts after 1100. Then expect moderate fire
behavior in Brown Duck Creek NW of Moon Lake and active fire behavior in Mackentire and Raspberry draws with short runs and up to 1/8-mile spotting. Light activity is expected in the West Fork of Rock Creek and in the upper portions of the Rock Creek canyon. Interior islands
will continue to hold heat.
Tomorrow, higher relative humidity will decrease fire activity in the West Fork of Rock Creek and the upper portions of Rock Creek Canyon. Moderate fire activity in the Brown Duck Creek area NW of Moon Lake, in Mackentire Draw and in Raspberry Draw.
