(dilynews.com) The Charlie fire burning north of Santa Clarita continued to grow on Sunday, charring thousands of acres in steep terrain that made battling the blaze difficult for firefighters. But in a sign of progress, an evacuation in place since Saturday night was lifted Sunday night.

Containment on the fire was brought to 20 percent by the evening, up from 10 percent in the morning, Los Angeles County Fire Department officials said on Twitter. The total acreage burned in the Castaic/Santa Clarita area stood at 3,380 on Sunday night — up from 3,000 acres Saturday night. The fire was burning grass, brush, chaparral and scattered trees.

There wasn’t any word on what might have caused the fire Saturday.

The city of Santa Clarita reported an evacuation was lifted Sunday night for structures on the west side of San Francisquito Canyon Road, from Lowridge Place to Camp 14. That order had affected some 20 residences, the Angeles National Forest said.

However, San Francisquito Canyon Road remained open to residents only. Officials hoped to open the road to all traffic by 6 a.m. Monday.

The city said Lake Hughes Road was closed between the Main Castaic Lake Boat Launch Ramp and Dry Gulch. Castaic Lake was open to boaters and campers on the east side of the lake only.

A hard closure was in place at Tapia Canyon and Valley View, the city said.

The evacuation center at Castaic Sports Complex that opened on Saturday was closed on Sunday.

Officials said they expected hundreds of firefighters to continue working on the blaze into the evening.

At just before 2 p.m., Santa Clarita officials said a large flare-up, producing a towering plume of black smoke, could be seen within the perimeter of the Charlie fire.

No structures were reported damaged. Officials said one firefighter suffered minor injuries Sunday and was taken to a hospital for treatment.

Firefighters dealt with continued intense heat on Sunday, with temperatures in the north Santa Clarita Valley in the 90s.
