The Trailhead Fire has blackened 3,387 acres and remains at 12 percent containment. It grew by less than 200 acres on Saturday.

Placer County residents have been allowed to return home. There are still 2,600 structures in El Dorado County that are threatened. Mandatory evacuations are in place in EDC, with several roads closed as well.

“The fire was most active on the southeast side, near Quartz Canyon and Little Bald Mountain, and on the northeast side near Volcanoville. It is not active on the north side,” according to CalFire. “Tonight crews will finish burnout operations started by the day shift. Other priorities for firefighters tonight are to patrol, hold, and improve existing containment lines; secure fire lines around structures; and prepare areas for crews to conduct burnout operations tomorrow.”

Two firefighters have been injured. One was treated for a heat illness and the other for a laceration.

The only campground on the Eldorado National Forest directly affected by this fire is Dru Barner, which is within the closure area. There might be some smoke in the Crystal Basin and Lake Tahoe areas.

No cause has been determined in the fire that started June 28 in the middle fork of the American River canyon south of Todd Valley.

The forecast is for hot and dry weather to persist throughout the weekend.

There will be a public meeting July 3 at 7pm at the Golden Sierra High School in Garden Valley.
