Good Progress On Ferguson Fire Overnight, Now 79 Percent Contained

MARIPOSA COUNTY – Firefighters continue to gain the upper hand on the Ferguson Fire, now estimated at 95,104 acres with 79 percent containment.

Crews continue to focus their efforts on the finger of the fire reaching toward Yosemite Valley, and stopping the spread to the North and South Rims of the Valley.

Overnight, firefighters took advantage of higher relative humidity and initiated a burning operation in the Grouse Creek drainage to prevent the fire from becoming established in the drainage and spreading across Wawona Road and further into the Park.

Firefighters will have a presence on all portions of the fire, however resources will be focused on the tunnel area of Big Oak Flats Road, Grouse Creek Drainage, and containment lines leading away from Badger Pass.

Evacuations will be lifted for Foresta as of 8 a.m. today. All residents will need to use the ENTRY POINTS at Highway 140 or Highway 120/ Big Oak Flat Road.

Big Oak Flat Road opens at 8 a.m. to residents and employees only.

There is no word yet on when closed portions of Yosemite National Park will reopen. There is still fire along the roads and dangerous fire-weakened trees continue to pose a hazard to both firefighters and the public.

Mop-up continues around Yosemite West and along Highway 41 south to Wawona. All lines are holding well.

The southern and western perimeters of the fire are in patrol status, and suppression repair work is underway.

A high pressure system has settled to the north of the fire area, creating an inversion over the fire. This inversion is acting like a cap over the fire trapping in air and moderating fire behavior. Today firefighters can expect similar weather conditions as the past few days; humidity
will be between 10 and 20 percent and winds light and variable.

The Ferguson Fire started on Friday, July 13, at 8:30 p.m., near Savage Trading Post on the south side of the Merced River canyon along Highway 140. The cause remains under investigation.

The estimated date for full containment is Aug. 15.

There are currently 1,889 personnel assigned to the incident including 135 engines, 22 crews, 18 water tenders, 23 dozers, 5 masticators, 14 helicopters, and fixed-wing tankers as conditions allow. Some personnel are being sent to other fires across the state including the Holy Fire in southern California.

Ten structures have been destroyed by the Ferguson Fire. Damage assessment teams have been able to get into some of the burn areas of the fire, and report that most of the 10 structures reported lost were in the Ned Gulch area on the north end of the fire. According to locals, these were historic mining operation structures that were being restored and used weekly for various types of outings and expeditions.

There have been 13 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 July 29 when he was struck by a tree during a firing operation.

Air quality issues

For information on air quality specific to Mariposa County visit http://www.mariposacounty.org/index.aspx?NID=1434. For additional information on air quality you can visit the AirNow website or the air fire smoke page.

The San Joaquin Valley Air Pollution Control District has also warned that a health caution is in place and smoke impacts will continue until the fire is extinguished.

Wildfire smoke is a mixture of gases and fine, microscopic particles that can cause health problems including triggering asthma attacks, aggravating chronic heart and lung diseases, and increasing the risk of heart attack and stroke. Where conditions warrant, people with heart or lung disease should follow their doctors’ advice for dealing with episodes of particulate exposure. People with existing respiratory conditions, young children and elderly people are especially susceptible to the health effects from these pollutants. Anyone being exposed to poor air quality or wildfire smoke should move inside to an air-conditioned environment.

Residents can check the San Joaquin Valley Air Pollution Control District’s wildfire page at www.valleyair.org/wildfires for information about any current wildfires and whether they are impacting the Valley. The District’s Real-time Air Advisory Network (RAAN) provides localized air quality data from an extensive air-monitoring network which allows Valley residents to track PM at any Valley address by visiting myraan.com.
