Smoke Continues To Hamper The Air Ops On Ferguson Fire

MARIPOSA COUNTY – It was another hot and humid day on the Ferguson Fire as it continues to push south and east.

As of this posting, a new estimate on the size of the fire has not come out. We will update here when that happens. This morning the fire was estimated at 17,319 acres with 5 percent containment.

Resources continue to arrive at the Incident Command Post in Ahwahnee from all over the region. There are currently 2,149 personnel assigned to the incident including 166 engines, 55 crews, 29 dozers, 21 water tenders, 18 helicopters, and fixed-wing aircraft as conditions allow.

Once again the dense inversion layer limited air operations over the fire for a good part of the day. While the smoke lifted early, it re-settled in the afternoon. Aircraft were able to get some work done, however at 2 p.m., Air Attack reported they were down to zero visibility again. At 2:10 p.m., all helicopter work was suspended, and it was around 6 p.m before aircraft could get back to work.

Before helicopters were grounded they were able to get some good retardant drops in on Ferguson Ridge and Sweetwater Ridge. The fire continues working its way north along Ferguson Ridge toward Highway 140 and down into Sweetwater Creek. Crews have line along Sweetwater Ridge and will be doing burnout operations tonight as needed.

Just before the evening briefing at 6 p.m., reports came in that a rockslide had come down in that area into Highway 140, and by 6:45 p.m. a Caltrans plow truck had arrived at scene to move the rocks and burning debris from the roadway.

Fire crews were successful in completing containment lines from just west of Indian Flat to west of Cedar Lodge, and crews have worked to control the fire’s spread along Cold Creek. The fire is expected to continue to move east across the slope through the night.

Firefighters have a good solid fireline around Cedar Lodge and Redbud Lodge, say fire officials. Structure protection continues along the Highway 140 corridor.

The fire continues to back down the mountain towards El Portal, but crews made good progress on the contingency line across from Highway 140 west of El Portal to tie in to the dozer line across Henness Ridge. They plan to tie that line in all the way across to Wawona Road to prevent the spread of the fire toward Yosemite West.

On the southern part of the fire dozers cut line south and east of Jerseydale along Footman Ridge, and tied it in to the line across the head of Skelton Creek. They also reinforced containment lines around Jerseydale and Mariposa Pines, and conducted burnout operations to remove the unburned fuel above the two communities so the fire has nothing to burn as it approaches.

As expected, hot and dry conditions persisted throughout the day. While the smoke lifted early, it re-settled in the late afternoon, again hampering visibility and grounding aircraft. Some thunderstorms were observed on the east side of the Sierra Nevada, but officials say they had little effect on the fire’s growth. More monsoonal moisture is expected tomorrow.

There are currently 108 structures threatened by the Ferguson Fire including 70 homes, 3 commercial buildings and 35 outbuildings. So far no structures have been lost.

There have been two firefighter injuries reported. There has been one fatality on the fire.

The Incident Command Post for the Ferguson Fire is now at the Ahwahnee Hills Regional Park. Please be aware of heavy fire equipment moving through the area.

The fire is under Unified Command with Cal Fire, U.S. Forest Service and the Mariposa County Sheriff’s Office. Tomorrow they will transition to a Type 1 Management Team – California Team 4.
