Crews battling the largest wildfire in California history took advantage of milder overnight temperatures to gain considerable ground in containing the blaze on Wednesday, a day after officials it would take until September to snuff it out.

The Mendocino Complex fire, which has scorched an area of Northern California almost the size of Los Angeles, was 47 percent contained on Wednesday morning, the California Department of Forestry and Fire Protection (Cal Fire) said. A day earlier, the fire was 34 percent contained.

So far, two firefighters have been injured fighting the blaze, which has consumed more than 300,000 acres. While sprawling, the wildfire was less destructive than last week's Carr Fire near Redding, destroying 75 homes and forcing the evacuation of more than 23,000 people. The Carr Fire destroyed more than 1,000 structures.
