"A 4,000-acre (1,620-hectare) wildfire in the Angeles National Forest in Southern California has forced the evacuation of some campsites as firefighters struggle to control the blaze, authorities said on Monday."
"The fire amid dry chaparral was only 5 percent contained and heavy smoke was visible from miles away. Authorities said it was not threatening any structures.
The fire broke out on Sunday in the San Gabriel Canyon area of the 655,000-acre (265,000-hectare) Angeles National Forest. About 12,000 weekend visitors, hikers and others were evacuated from the area, said U.S. Forest Service spokeswoman Angie Lavell.
The Angeles is less than 15 miles from downtown Los Angeles at its southern end. It is one of the most heavily visited national forests, with about 30 million annual visitors."
