Date Set To Reopen Highway 41 Inside Ferguson Fire

YOSEMITE – As crews continue their work to get final containment on the northern edge of the Ferguson Fire, the estimated acreage remains unchanged at 96,824 acres, and officials are reporting the containment at 87 percent for the fourth day in a row.

Highway 41 (Wawona Road) between Chinquapin Junction (Yosemite West) and the Tunnel View is expected to open on Friday, Aug. 24, at 8 a.m. Hazard tree removal continues, and crews are still dealing with roll-out as rocks and debris come down into the roadway where vegetation has been lost.

Yesterday, firefighters secured the last area of active fire near Turtleback Dome and Elephant Rock. All of the Ferguson fire is now in a patrol/mop-up and repair phase. During the heat of the day, some interior islands of unburned vegetation are igniting but officials say they are not a threat to containment lines.

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

All other areas of Yosemite National Park are now open to the public (see details below).

There are three phases of recovery following wildfires: Fire Suppression Repair, Burned Area Emergency Response (BAER) and Long-Term Recovery and Restoration. The Fire Suppression repair is currently ongoing with the repair of hand and dozer fire lines, roads, trails and safety zones used during fire suppression efforts.

The BAER team is on site doing an assessment of burned areas in order to identify imminent post-wildfire threats to human life and safety, property, and critical natural or cultural resources on public lands. Based on the assessment, corrective actions are proposed to protect fire-damaged areas.

The final phase of recovery is Long-Term Recovery and Restoration which utilizes non-emergency actions to improve fire-damaged lands that are unlikely to recover naturally.

There are currently 920 personnel assigned to the incident with equipment that includes 43 engines, 18 water tenders, 10 dozers, 6 crews, 4 helicopters and 3 masticators.

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.
