The fire, which has been burning in the area of Niles Canyon and Palomares roads since Thursday afternoon, has been 80 percent contained since 8:45 p.m. that night.
While officials had hoped to have the blaze fully contained by this morning, a Cal Fire spokesman said a full perimeter has not been established because it is burning in difficult terrain.
"We're going to be out there all day," said Chris Morgan, a fire prevention specialist with Cal Fire. "It's going to be quite a process."
Morgan said the difficulty is due to the extremely steep, rugged and rocky terrain. Rocks and debris rolling down hillsides also are causing problems.
Three firefighters suffered minor or moderate injuries due to falling rocks and debris Thursday, according to Cal Fire Battalion Chief Jim Crawford.
A fourth fire fighter suffered minor heat-related injuries, Crawford said. No additional injuries have been reported.
Shortly after the fire was reported Thursday, about 300 firefighters from Cal Fire and local agencies were combating the flames, according to Crawford.
Morgan said there are still a few crews and engines on the fire today, but the number of personnel responding is "nowhere near what it was" Thursday night.
Palomares Road was closed between state Highway 84 and Interstate Highway 580 for most of Thursday afternoon and evening, but it was reopened at midnight, according to the California Highway Patrol.
