Successful Firing Operations Increase Containment On Ferguson Fire

MARIPOSA COUNTY – Firefighters continue to focus on tactical firing operations across the Ferguson Fire, which is now estimated at 57,846 acres and is now 33 percent contained.

Officials estimate there are 2,846 structures threatened by the fire, and one non-residential structure has been destroyed.

Crews made good progress overnight as they continued to widen and strengthen containment lines on the east, north and south.

Inside Yosemite National Park, firefighters along the eastern perimeter got within a mile of Wawona Campground with nighttime firing operations, working south along Wawona Road (Highway 41). When completed, the operation will add about six miles of improved containment line along the southwest corner of the fire.

On the section of fire burning north of the Merced River on the Stanislaus National Forest, crews will look for opportunities to conduct tactical burning operations up past Yosemite’s Merced Grove of giant sequoias and along the Thirteen Road toward Pilot Peak. Firefighters intend to link these two firing operations within the next two days by burning along Pilot Ridge on the Mariposa-Tuolumne county line.

On the eastern perimeter, crews are monitoring a portion of the fire that slopped over a containment line a few days ago about a mile southeast of El Portal. The fire is burning in steep terrain with an excessive amounts of beetle-killed trees, making it difficult to access. Crews are scouting areas to construct indirect containment lines while making use of water and retardant drops to keep the fire within its current boundaries.

Across the southern perimeter near Roundtree Saddle, spot fires from the previous day showed increased activity, but crews were able to keep them within their containment lines.

Firefighters continued to make significant progress firing containment lines from Roundtree Saddle toward Chowchilla Mountain Road, with hopes to connect to Wawona Campground within the next two days.

Natural resource specialists began 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.

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 widening or extending 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.

During all tactical firing operations on the Ferguson Fire, firefighters and law enforcement maintain a presence in evacuated communities to ensure home and structure safety.

There is now an estimated date for full containment of Aug. 15.

There are currently 3,638 personnel assigned to the incident including 219 engines, 93 crews, 46 water tenders, 72 dozers, 14 helicopters, and fixed-wing tankers as conditions allow.

There have been eight firefighter injuries reported, and numerous instances of heat exhaustion-type symptoms. There have been two fatalities on the fire; HFEO Braden Varney was killed in a dozer rollover accident on July 14, and Brian Hughes, Arrowhead Hotshot Captain, lost his life yesterday when he was struck by a tree during a firing operation.
