Mendocino Complex Fires 20,000 acres larger than any other in California history

The Mendocino Complex Fires, which are composed of the Ranch Fire and River Fire, will go down as the largest in California history.

They've grown to a combined 305,152 acres. To put that in perspective, that's larger than the sprawling city of Los Angeles.

Before this year, the largest wildfire in state history was last year's Thomas Fire, which burned 281,893 acres.

Another fire that is currently burning, the Carr Fire, just entered the top 10 list. That fire has so far killed seven people and is among the most destructive fires in state history.
