Firefighters will spend the day trying to fully contain a sprawling Placer County wildfire that has displaced almost 300 people since Wednesday.

About 1,400 firefighters are battling the Robbers Fire, which began at 3:30 p.m. Wednesday in Shirttail Canyon between Colfax and Foresthill, about 40 miles northeast of Auburn. The fire has burned 1,157 acres and is 10 percent contained.

Firefighters scored a win late Thursday when they stopped the blaze from moving into a steep canyon that would have funneled the flames north toward the small community of Colfax, said Cal Fire spokesman Brice Bennett. Firefighters will spend Friday shoring up their defenses at the canyon’s mouth, he said.
