Minimal Growth On Ferguson Fire, Weather Delays Some Firing Operations

MARIPOSA COUNTY — Firefighters held the growth of the Ferguson Fire to just 228 acres today. The fire is now estimated at 58,074 acres and is still 33 percent contained.

Officials announced earlier today that the closure of some portions of Yosemite National Park will be extended to Aug. 5.

Firefighters cannot always count on being able to conduct firing operations as planned. If winds and humidity levels work against them, they have to postpone planned operations. That has happened during a few operational periods on this fire, but crews continue make improvements to their section of the line and are ready to go when conditions allow.

North of the Merced River where the fire is burning on the Stanislaus National Forest, crews continued to monitor the portion of the line on the west that has been fired, and are doing mop-up. They did not have the opportunity to conduct firing operations as weather conditions were not favorable last night. Conditions were also not optimal throughout today’s shift, but everything is in place and they continued to do prep work and established check line for anticipated firing operations tonight on Thirteen Ridge up to Pilot Peak.

On the eastern portion of that big box, crews were able to fire partway up toward the Merced Grove along Forest Road 2S20 last night, but the weather didn’t cooperated for firing on the day shift. Crews worked on removing hazard trees and prepped the line for burning.

Once firing along the east and west flanks has been complete, planners anticipate firing south off Pilot Ridge in the next 24 to 48 hours. Structures in the Anderson Valley area are being protected by firefighters as these operations are being carried out.

In response to the danger posed by the fire on the north, and the heavy fire equipment traffic, Stanislaus National Forest Supervisor Jason Kuiken has signed a forest order closing several Groveland Ranger District roads and trails impacted by the Ferguson Fire.

This closure is based on the current and expected fire behavior and will be in effect until Sept. 30, or until replaced or rescinded. Click here for details and a map of the closure.

With the good progress along the Merced River, evacuations were lifted yesterday from Savage Trading Post – the point of origin of the Ferguson Fire – east to El Portal. Old El Portal, Foresta and Yosemite West remain under a mandatory evacuation order, and Highway 140 is open to residents only (see details below). It is not yet open to the public.

About a mile southeast of El Portal, a slopover east of the line continues to present a challenge. Hazard trees and rocks are falling continuously in the steep, dangerous terrain, and fire managers are not willing to put crews on the ground there; it’s just not safe. The fire is about 200 acres as of 6 p.m. today.

Planners are using the road systems, a rock scree and a ridge system to draw a box around the slopover. Crews began constructing indirect lines and performed tactical burning along a road south of the slopover 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.

Exacerbating the problem of the slopover is the dense inversion, which prohibits air operations until very late in the day. A heavy helicopter was able to get up over the fire late yesterday, but could only work for a couple hours.

Inside Yosemite National Park, crews burned the west side of Highway 41 last night, down to within a mile of Wawona Campground. Firing operations will continue south this evening as they work their way down to tie in to the Merced River before continuing on to connect with the line coming from the west across Chowchilla Mountain Road.

On the southern perimeter, firing operations continued east to the Crow Peak area last night. Crews continued that burning today over to Battalion Pass with good success, now that they have moved out of the heavy fuels and unfavorable winds near Roundtree Saddle. There were no spots over the line today, and the fireline in the Chowchilla Mountain Road area is now 1,000 feet deep in some places.

Planners are estimating 24 to 48 hours to complete the southeast corner of the fire, and connect the eastern and southern firelines, if conditions are favorable.

The slopover north of Ponderosa Basin continued to be troublesome overnight, but there are sufficient resources in there to handle it, and there were no problems today. Residents in Ponderosa Basin were allowed to return home yesterday, and the fire advisory was lifted at 6 p.m. today

The western perimeter remains quiet up through Jerseydale, Mariposa Pines, and on up Sweetwater Ridge. Residents will start seeing some equipment over the next few days as repair efforts begin. Firelines will be repaired and measures taken to prevent erosion where the ground has been disturbed due to suppression work.

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

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

There are currently 3,558 personnel assigned to the incident including 203 engines, 95 crews, 43 water tenders, 62 dozers, 14 helicopters, and fixed-wing tankers as conditions allow.

There have been nine 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 on Sunday when he was struck by a tree during a firing operation.

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.
