The biggest wildfire in Los Angeles County history is finally fully contained.

The U.S. Forest Service says the 250-square-mile Station Fire was declared 100 percent contained at 7 p.m. Friday, 52 days after it began.

Authorities had kept the containment figure at 98 percent since late September even though for weeks there were few signs of fire in the Angeles National Forest.

After moderate rain last week, crews hiked in and completed containment lines on a portion of the fire in the San Gabriel Wilderness area.

Two firefighters were killed during the blaze and 89 homes were lost.

The fire got its name because it started in the vicinity of a ranger station. Investigators say the cause was arson.
