Visitation for firefighter Braden Varney, who died in the Ferguson Fire, has been scheduled for 2 p.m. until 6 p.m. Sunday at Franklin and Downs Funeral Home, 1050 McHenry Ave., in Modesto. The visitation is open to the public.

Four firefighters have been injured in the Ferguson Fire, which has grown to 27,129 acres, an increase of 2,500 acres since Friday morning, the U.S. Forest Service said Saturday.

No information was released about the injuries sustained or when the firefighters were injured. One firefighter died July 14, the day after the fire started in the Sierra National Forest, and injuries to two had been announced previously.

The body of heavy equipment operator Braden Varney, 36, with the Madera-Mariposa-Merced Unit was found beside his bulldozer, which had overturned near Highway 140.

Visitation for Varney has been scheduled for 2 p.m. until 6 p.m. Sunday at Franklin and Downs Funeral Home, 1050 McHenry Ave., in Modesto. The visitation is open to the public. Services will be held at 11 a.m. Monday at the House Modesto.

The Forest Service announced at 10 a.m. Saturday a mandatory evacuation for Yosemite West, a community of resort homes near the southern entrance to Yosemite National Park.

The Forest Service attributed the growth to atmospheric conditions.

"The inversion layer lifted and fire activity increase in many areas of the fire footprint," a news release from the Forest Service said.

The fire jumped over Highway 140 and the Merced River in an area too rugged for air tankers to fly.

"Both air and ground resources engaged the new fires early but were unable to make headway in the steep, rugged terrain," the news release said.

Forest Service spokesman Jim Mackensen told KQED that it was likely the fire will spread to at least the far western edge of Yosemite National Park.

"It's still miles away from that, but given the conditions, the terrain, it's probably one of those things we're not going to be able to prevent," he told the radio station.

Today, firefighters are looking for the best place to make a stand against the spot fire.

On Friday, the Forest Service called the fire "extremely active" and said they did not know when it might be contained.

The fire was moving to the south and east of the Granite Ridge area.

Firefighters were holding the line along the southern and western borders near Jerseyville and Mariposa Pines, the Forest Service said.

Total personnel had grown to just over 2,800 Friday.

Tuolumne-Calaveras Unit resources that have been assigned to the Ferguson Fire include six engines, four crews, two dozers and 12 supervisors — for a total of about 90 personnel, Melinda Shoff with Cal Fire TCU in San Andreas said Friday afternoon.

Resources fighting the blaze Friday afternoon included 204 engines, 70 hand crews, 40 bulldozers, 38 water tenders, and 17 helicopters.

The blaze, which started next to Highway 140 west of El Portal, was estimated to be 7 percent contained as of Friday afternoon.

The Ferguson Fire was first reported at 9:36 p.m. July 13 next to Highway 140 in the Merced River Canyon west of Yosemite National Park.

The blaze was threatening more than 200 homes, though none had been damaged or destroyed as of Saturday morning.

According to InciWeb, mandatory evacuations remained in place Friday afternoon for: “El Portal Trailer Court, Incline Road from Clearing House to the last BLM campground, Jerseydale/ Mariposa Pines, Cedar Lodge/Indian Flat Campground, Savage’s Trading Post and Sweetwater Ridge, and Incline Rd from Clearing House to the Foresta Bridge.”

There was an American Red Cross evacuation shelter set up at New Life Christian Fellowship Church at 5089 Cole Road in Mariposa.

The town of Foresta, located within Yosemite National Park about 2 miles northeast of El Portal, was placed under placed under an evacuation advisory Friday morning.

Highway 140 was closed from 1.9 miles east of Midpines to the Cedar Lodge area.

The fire is burning in steep terrain on Sierra National Forest land with pockets of bark-beetle killed trees and heavy timber. Incident commanders are still investigating the cause of the fire.
