 Lions Fire Update


The Lions Fire is estimated at 7,549 acres with 65% containment, showing an increase of 55 acres. However, the fire could not be accurately mapped due to smoke inversion and growth is likely greater than what mapping reflects. There are 180 personnel committed to the fire, including 7 crews, 4 helicopters, and a pack string of mules from the Stanislaus National Forest.


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 by securing the southwest corner and keeping the fire out of the Middle Fork San Joaquin River drainage. The fireline along the northeast flank of the fire remains secure (south of Fern Lake). Burning operations were suspended yesterday due to the wind event and crews focused on holding and strengthening the line. This focused effort protects developed areas in Devils Postpile National Monument, Reds Meadow, and Mammoth Lakes.


Along the western flank, crews are using trail networks and rock barriers for containment lines. Crews also continue to construct direct and indirect fireline along the southwest and west flanks 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 as air conditions permit.


The area has experienced approximately 50% tree mortality from bark beetles and drought conditions. Yesterday’s observed fire activity included backing, flanking, and single-tree torching. In the south and west flanks the fire is moving downslope.


Hot and dry conditions remain in the forecast with a Red Flag warning for gusty winds and low humidity until 10 pm tonight.


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).
