Firefighters get control of brush fire near San Dimas

A brush fire that broke out early Friday near San Dimas has been largely controlled, officials said.

The fire broke out around San Dimas Canyon and Golden Hills roads around 4 a.m., according to a tweet from the U.S. Forest Service. By noon, the blaze had consumed about 100 acres and was 25% contained. Firefighters stopped forward progress on the blaze about five hours after it began.

“The fire is no longer moving. It’s no longer spreading,” Los Angeles County Fire Department spokesman Marvin Lim said. “We’re still working on containing it fully, but there’s no more active flame that’s spreading.”

Three firefighters suffered minor “lower-extremity” injuries while battling the blaze, Los Angeles County Fire Department spokesman Sean Ferguson said. Two of the firefighters were with L.A. County, and one was with the Forest Service. He could not confirm whether the injuries were burns.

The firefighters were transported off the hillside by helicopter and taken to a nearby hospital.

The fire was burning in dense vegetation within the San Dimas experimental forest, said Forest Service spokesman Andrew Mitchell. Experimental forests are areas designated for research; the one in San Dimas was established in 1933 and is the only such forest in Southern California.

Firefighters battled the fire from the air and on the ground, and Lim said they would continue to lay hose lines throughout the day.

No homes were threatened by the blaze.

Southern California had experienced dry and warmer-than-normal temperatures over the past two days, but back-to-back storms, the first of which is moving in Friday, will bring cooler temperatures and a good chance of rain and mountain snow, the National Weather Service reported Thursday.

The cause of the fire is still under investigation.
