Good Progress Overnight On Ferguson Fire, Now 86 Percent Contained

YOSEMITE – Firefighters continue their efforts to contain the last remaining active fire, burning near the entrance to Yosemite Valley between Highways 41 and 140.

The Ferguson Fire is now estimated at 96,457 acres and is 86 percent contained

The Mariposa Grove of Giant Sequoias and Wawona reopen today at 9 a.m. (see details below). Yosemite Valley is scheduled to reopen to the public tomorrow, Aug. 14, at 9 a.m.

Crews have made good progress on firing operations along Highway 41 between Glacier Point Road and Elephant Rock, and the fire continues to back slowly down to the Merced River. There are still unburned pockets of vegetation within the containment lines, but the risk of spot fires has been reduced significantly.

The fireline has now been secured between Yosemite West and Glacier Point Road (Chinquapin Junction). This increase in containment near the Yosemite Ski and Snow Board Area (Badger Pass) has allowed the spike camp that was evacuated when the fire crossed Highway 41 on Aug. 3, to be reestablished at the ski area to reduce drive time to this portion of the fire. All other personnel remain at the Incident Command Post in Ahwahnee.

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

As containment on the fire grows, the number of personnel assigned to the incident continues to drop and is now at 1,020.

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.
