Ferguson Fire Wildfire
News – 8/12/2018

Incident Start Date: 7/13/2018 Cause: Under Investigation Size: 95,947 acres Containment: 83%

Incident Type: Full Suppression Vegetation Type: Brush and timber

Unified Command Agencies: U.S Forest Service, National Park Service and Interagency Command Team 3

Resources Assigned: Engines: 180 Water Tenders: 9 Helicopters: 14 Crews: 9 Dozers: 17 Masticators: 5 Total Personnel: 1,142

Current Situation: Firing operations were completed yesterday to Elephant Rock. (Elephant Rock is a formation approximately one and one half mile west of Tunnel View). Work remains to reinforce containment lines to ensure the fire does not spread into Yosemite Valley. Sprinkler systems are active at the base of Elephant Rock to prevent the fire from spotting beyond the established hand line.

Today, hand crews and engines are patrolling Wawona Road along the burnout operation, watching for spot fires outside the containment lines. These spot fires continue to be a threat in holding the fire perimeter. Helicopters have been effective in helping crews on the ground extinguish detected spot fires.

Progress has been made in extinguishing hotspots on the service road leading to Badger Pass and containment increased along this road, yesterday. Today, firefighter will be reinforcing the hand line from Badger Pass northwest to Wawona Road.

Elsewhere on the fire, crews are backhauling, or bringing back to camp, equipment, tools and hose that was used in the suppression efforts, but now are no longer needed. Over 200 miles of hose was used on the Ferguson fire and used hose must be brought back to camp and rehabilitated to use on the next fire.

Weather: Similar to yesterday’s forecast, relative humidity will be higher at 15 to 30 percent. The monsoonal moisture will move across the fire area and the fire area may receive out flow winds from storms, developing over Sierra Crest.

Highway 120 also known as Yosemite’s Tioga Road is open through the Park, this includes Tuolumne Meadows Visitor Center, White Wolf Campground, Soda Spring, Tenaya Lake, and Lembert Dome.
