Ferguson Fire Evening Update for July 31, 2018

Ferguson Fire Wildfire
News – 7/31/2018

Firefighters made progress toward full suppression on the Ferguson Fire. Officials reported the fire grew by 228 acres throughout the day and was at 58,074 acres as of 6 p.m. Containment is at 33 percent.

Firefighters prepared for nighttime tactical firing south along Wawona Road (Highway 41) toward Wawona Campground. Crews along the southern perimeter widened containment lines by up to 1,000 feet in some areas near Chowchilla Mountain Road using firing operations. The line should be wide enough to contain the spot fires that have occurred in the area in recent days.

Firefighters began constructing indirect fire lines to intercept a spot fire that had jumped containment lines a few days earlier south of El Portal. Crews performed tactical burning along a road south of the fire in response to the fire’s southeasterly movement. Additional personnel have been sent to the Foresta area in case the fire shifts to a more northeastern direction. Steep and inaccessible terrain have made direct attack on the fire difficult.

On the north end of the fire, crews will conduct nighttime burning operations northbound to Yosemite’s Merced Grove of giant sequoias and along the Thirteen Road toward Pilot Peak.

Area residents can expect to see increased smoke during the next few days as firing operations continue. Tactical firing is an effective way to reduce fuel loads while simultaneously buffering containment lines. It can reduce the duration and intensity of wildfires, particularly by decreasing available fuels and weakening the fire as it approaches containment lines.

Air quality is likely to decrease as a result of increased smoke from the firing operations. Residents can monitor the latest air quality and health advisories at:



Natural resource specialists have begun surveying the western side of the fire today to assess areas requiring repair and mitigation. Firefighters, in conjunction with resource advisors, play an important role in helping the landscape recover from containment lines and other suppression tactics.
