The most active portion of the fire remains on the western flank in the Cargyle Creek Drainage of the Sierra National Forest. Increased fire activity is expected today.
Crews continue to make progress on the fire. The fireline along the northeast flank of the fire remains secure (south of Fern Lake) and crews are slowly strengthening this line to the west towards Corral Meadows with burnout operations. This line provides a buffer, keeping the main fire from spotting into King Creek to protect developed areas in Devils Postpile National Monument, Reds Meadow, and Mammoth Lakes. Burnout operations will continue to occur in the interior to secure the perimeter from fire runs.FERGUSON FIRE UPDATE 8.4
Along the western flank, crews are using trail networks and rock barriers for containment lines. Crews also continue to construct fireline along the southwest flank in an effort to keep the fire crossing the San Joaquin River. Helicopters are supporting them by cooling the fire’s edge with water drops.
The area has experienced approximately 50% tree mortality from bark beetles and drought conditions. Fire activity includes short duration crown runs and group torching. The south and west flanks are expanding slowly, and in some locations the fire is moving downslope.
Hot and dry conditions remain in the forecast. A Red Flag warning is in effect today from 10 am to Sunday 5 am for gusty winds and low humidity.
