Ferguson Fire Reaches Merced River, Line To Elephant Rock Secured

YOSEMITE –  For the past week the Ferguson Fire has continued the slow process of backing down to the Merced River from Highway 41. It has now reached the river across most of the line and the acreage has increased very slightly to 96,824 acres.

The fireline from Glacier Point Road north to Elephant Rock has now been shown as secured in the morning mapping (see map below). However the official estimate of containment remains at 87 percent.

Firelines are in place and holding across the northern perimeter from Elephant Rock down to the river.

Though there have been a few flare-ups reported on the northeast section of the fire, they have all been within the containment lines and were quickly handled.

The date for full containment has been moved to Wednesday, Aug. 22, however interior parts of the forest will continue to smolder and burn for some time, causing lingering smoke.

The remainder of the fire is in mop-up and patrol status and restoration and suppression repair is underway.

All areas of Yosemite National Park are now open to the public except the section of Highway 41 (Wawona Road) between Wawona and the Tunnel View (see details below). There is no estimated date to reopen Highway 41. Crews are still dealing with roll-out as rocks and debris come down into the roadway where vegetation has been lost.

Burned Area Emergency Response (BAER) Teams have arrived and are continuing to assess the burned areas on Sierra and Stanislaus National Forests and Yosemite National Park. The BAER teams determine the level of potential risk as well as the appropriate and effective emergency stabilization measures needed in order to help reduce the risk from potential flooding and debris flows as winter weather arrives.

There are currently 833 personnel assigned to the incident with equipment that includes 39 water tenders, 11 masticators, 7 dozers, 3 crews and 3 helicopters.

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.

As of Aug. 14, some 1,254 acres had burned on the Madera-Mariposa-Merced Unit, 65,460 acres on Sierra National Forest, 18,892 acres on the Stanislaus National Forest, and 11,000 acres on Yosemite National Park land.

Ten historic structures have been destroyed, though no inhabited homes have been lost.

There have been 19 firefighter injuries reported. 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.
