The East Fire in the hills above Glendora was 75% contained Saturday after burning 149 acres of brush.
“Firefighters (will) continue to work on keeping the fire within the same footprint by increasing containing lines,” officials from the Angeles National Forest reported. “Plus, they will work on extinguishing hot spots within the fire perimeter.”
Officials said the East Fire is not threatening any structures or homes in the area.
Glendora Mountain Road, from Glendora to the East Fork Road, and Glendora Ridge Road, from Mount Baldy Road to Glendora Mountain Road, were closed as of 4:30 a.m. Friday.
The cause of the fire was unknown.
It was first reported at about 2:15 p.m. Thursday and was burning along Glendora Mountain Road and East Fork Road within the San Gabriel Mountains National Monument, according to the U.S. Forest Service.
Firefighters from Cal Fire, the U.S. Forest Service and the Los Angeles County Fire Department were dispatched to the Angeles National Forest to douse the flames.
