A 12- to 15-acre wildfire was 20 percent contained north of Big Bear Lake on Saturday. It did not immediately appear to threaten any structures, officials said.
The fire was reported about 5:30 p.m. near a fire station in the Fawnskin area (map) of San Bernardino County. The blaze was spreading among trees at a moderate pace, said Cal Fire spokesman Glenn Barley.
U.S. Forest Service officials tweeted some updates about the fire, saying three airtankers are dropping flame retardant and firefighters had constructed a line around three-quarters of the fire.
The blaze erupted on a day that saw several fires break out in Southern California, the largest of which burned at least 170 acres and prompted evacuations in Monrovia.
