Yosemite Valley Reopens Today As Ferguson Fire Nears Containment

YOSEMITE – Crews continue to make good progress containing the Ferguson Fire on the northern perimeter just outside the entrance to Yosemite Valley.

The fire is now estimated at 96,606 acres and is 86 percent contained.

Yosemite Valley reopens to the public today at 9 a.m., after being closed since July 25 due to fire suppression activities and heavy smoke. Visitors can access the Valley via Highway 140 from Mariposa or on Big Oak Flat Road from Highway 120. Highway 41 remains closed between Wawona and the Tunnel view (see details below).

On the northern perimeter near Elephant Rock, the process of backing the fire slowly down from Highway 41 to the Merced River continues. Visitors should expect to see smoke as interior fuels burn themselves out.

The remainder of the fire is in mop-up and patrol status, lines have been secured, and suppression repair efforts are ongoing.

Crews are backhauling the equipment, hose and tools that were 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 for use on the next fire.

Operations on the fire are being conducted under a joint delegation of authority from the Sierra and Stanislaus National Forests, and Yosemite National Park.

Some 1,254 acres have 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.

As containment on the fire grows, the number of personnel assigned to the incident continues to drop and is now at 910.

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 Ferguson Fire is now the largest fire in the history of the Sierra National Forest. The estimated date for full containment is Wednesday, Aug. 15.

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.
