A fire that burned nearly acres of brush in steep terrain above a San Gabriel Valley foothill community was fully contained as authorities feared a brutal fire season ahead.
Firefighters began "making great progress" on the small brush fire after water-dropping helicopters arrived at daybreak Wednesday to attack the fire.
The fire was reported at 4 a.m. in San Dimas, about 20 miles east of Pasadena. No structures were threatened and no evacuations were ordered, according to fire officials.

The fire burned up a steep hill near the 2100 block of Terrebonne Avenue, just north of the San Dimas Canyon Golf Course. The golf course remained open.
"We feel like we're making great progress," Los Angeles County Fire Inspector Keith Mora said early Wednesday. "Daybreak allows us to do a lot more than we were in the middle of the night."
The fire did not cause any injuries or threaten any homes, Los Angeles County Fire Department Supervisor Michael Pittman said.
The cause of the fire remained under investigation, the dispatcher said.
Firefighters are bracing for the worst of the fire season during a historic drought and when temperatures and humidity are ripe for big blazes.
"Right now, it's hot and it's dry," said Capt. Brian Jordan, of the Los Angeles County Fire Department.
Authorities were investigating multiple fires in the area in the last month.
Residents were on edge.
"We've been a little concerned," said Midge Hill, adding she was encouraged by the water-dropping helicopters in the area.
