Lions Fire Update


The Lions Fire is estimated to be 6,648 acres and 60% contained, showing an increase of 118 acres yesterday. However, the fire could not be accurately mapped due to smoke inversion and growth is likely greater than what mapping reflects.


Fire activity remains on the western flank, into heavy fuels in the Cargyle Creek Drainage on the Sierra National Forest. Similar fire activity is expected today. The Lions Fire did not see any measurable precipitation yesterday.


Crews completed burning operations along the northeast flank of the fire (south of Fern Lake), strengthening the control line and improving a buffer to keep the main fire from spotting into King Creek and further protecting Devils Postpile National Monument, Reds Meadow, and Mammoth Lakes. Approximately 50+ acres were burned yesterday and burnout operations will continue to occur in the interior to secure the perimeter from fire runs.


Along the western flank, crews continue to scout trail networks and rock barriers to determine the best location for new containment lines. Crews also continue to construct fireline along the southwest flank of the fire. 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.

The Lions Fire currently has 180 total personnel assigned, including seven crews and four helicopters.


Hot and dry conditions remain in the forecast with the potential for continued thunderstorms for the next several days. A Red Flag warning is in effect Saturday August 4 from noon to 10 PM for gusty winds and low humidity.


The Reds Meadow Road and all services in the Reds Meadow Valley, including Devils Postpile National Monument and Rainbow Falls, remain open.


Closures: There is an emergency trail closure for the Fern Lake and Beck Lake Trails on the Inyo National Forest and emergency trail closures and a Forest Order to close the area on the Sierra National Forest (west of the North Fork of the San Joaquin River, north of the Middle Fork of the San Joaquin River and South of Iron Creek).
