Ferguson Fire Grows To Over 21,000 Acres, Thunderstorms Possible

MARIPOSA COUNTY – The Ferguson Fire, burning south of Highway 140 in Mariposa County, has now grown to 21,041 acres and is 7 percent contained.

As of this morning, no structures have been damaged or destroyed, and no further evacuations have been ordered.

There are currently 2,149, personnel assigned to the incident including 166 engines, 55 crews, 29 dozers, 21 water tenders, 18 helicopters, and fixed-wing aircraft as conditions allow.

The fire showed moderate growth overnight, say fire officials. Crews worked late to strengthen the line around Jerseydale and along Sweetwater Ridge, and to complete containment lines along Highway 140 at Cold Canyon.

The fire continued to back west into Sweetwater Creek, north onto Ferguson Ridge, and north toward Highway 140.

In the Jerseydale area, the fire continued to back down the hill. Crews have been conducting burnout operations in that area to to remove fuels ahead of the fire’s approach. Structure protection is a top priority in this area, and firefighters will continue to work on indirect lines (containment lines placed ahead of the fire’s active edge) to protect the community.

Today, crews will continue to build and improve indirect lines along Sweetwater Ridge and from Highway 140 southeast to the Wawona Road (continuation of Highway 41 in Yosemite National Park) along Henness Ridge.

The chance of thunderstorms is predicted to increase today. Thunderstorms can produce erratic winds, causing the fire to change direction quickly and unexpectedly. This is especially dangerous for firefighters working on constructing indirect containment lines as a sudden shift in wind can cause fuel between them and the fireline to burn.

Though the west entrance (El Portal) to Yosemite National Park on Highway 140 is closed, the park remains open. For information on Yosemite National Park, go to nps.gov/yose or call 209-372-0200.

There are currently 108 structures threatened by the Ferguson Fire including 70 homes, 3 commercial buildings and 35 outbuildings. So far no structures have been lost.

There have been two firefighter injuries reported. There has been one fatality on the fire.

The Incident Command Post for the Ferguson Fire is now at the Ahwahnee Hills Regional Park. Please be aware of heavy fire equipment moving through the area.

The fire is under Unified Command with Cal Fire, U.S. Forest Service, Yosemite National Park and the Mariposa County Sheriff’s Office. Today management of the fire will transition to a Type 1 Management Team – California Team 4.
