The North fire, which burned roughly 2,100-acres near Acton, was 60 percent contained as of yesterday, Gougis said. That fire started around 2:30 p.m. Sunday and grew quickly south of the Antelope Valley (14) Freeway in an area about 11 miles east of Santa Clarita. It was unknown if the fire was caused by lightning, but “it’s obviously something we’re looking at,” said Stanton Florea of the U.S. Forest Service. “The total acreage might increase a bit, but they are predicting full containment by Friday,” said Fire Information Officer Ed Gililland with the Angeles National Forest. More than 800 firefighters, five air tankers and eight helicopters were deployed against the blaze. Residents of about 25 homes voluntarily evacuated Monday afternoon in the 7000 block of Soledad Canyon Road, and an evacuation shelter was opened at High Desert Middle School at 3620 Antelope Wood. No major injuries have been reported in either fire, although a firefighter was treated for heat exhaustion.160Want local news?Sign up for the Localist and stay informed Something went wrong.
