Crews working all night continued to build containment lines around a wildfire that scorched 250 acres of dry brush in the San Gabriel Mountains northeast of Los Angeles.
US Forest Service spokesman Nathan Judy said Wednesday the blaze near the foothill community of Azusa is 72 percent contained.
There are no active flames and no homes are threatened.
Full containment is expected Friday.
Meanwhile firefighters attacked a blaze that briefly threatened 30 rural homes near the San Bernardino mountains, hoping to get the upper hand on the 200-acre fire before winds were expected to pick up.
The second fire erupted shortly before 4 p.m. Tuesday near the heavily traveled Cajon Pass and ran through the brushy foothills of the San Bernardino Mountains.
Some 30 homes were initially evacuated as a precaution.
Helicopters and a DC-10 made water drops and by late Tuesday had reduced much of the blaze to white smoke. Containment figures were not immediately available.
