A small wildfire is underway at Sugar Pine Road and Big Reservoir Lane, about five miles northeast of Foresthill in Placer County, according to a Cal Fire tweet Friday afternoon.
Sugar Pine Road is currently closed, officials said, and visitors are being asked to avoid the area.
California Department of Forestry and Fire Protection and Foresthill Fire Protection District are assisting U.S. Forest Service officials with the Sugar Fire, said Joe Flannery, a spokesman for the Tahoe National Forest.
By 5:30 p.m., the fire had burned 25 to 35 acres with more than 100 personnel responding, Flannery said.
The personnel included four hand crews, six engines, two helicopters, two water tenders, a bulldozer, Flannery said. Three air tankers that were performing fire retardant drops during the afternoon had been dismissed.
Crews will be doing fire containment through the night, Flannery said. The cause of the fire is under investigation.
The fire started at 12:38 p.m. Friday, said Mary Eldridge, a Cal Fire spokeswoman.
“We’ve got a north wind so every resource available is heading out there,” Eldridge said at about 3 p.m. Friday.
The fire is located two miles southeast of Sugar Pine Reservoir and the Forbes Creek campground and about 10 miles east of Colfax.
This is the first wildfire in the four-county Sacramento region this year. There have been several other small wildfires in Butte County.
