One of two wildfires building miles apart in Northern California grew overnight, burning through dry vegetation in rugged terrain.
The California Department of Forestry and Fire Protection said Tuesday the blaze burning in Mendocino, Lake and Colusa counties has scorched 378 square miles (979 square kilometers). It’s only 20 percent contained.
But fire crews made progress against the other blaze, which is now 78 percent contained.
Late Monday, the wildfires known as the Mendocino Complex, became the state’s largest wildfire in history.
Officials say together the blazes about 100 miles (259 kilometers) north of San Francisco have charred 455 square miles (1,178 square kilometers).
That surpasses a wildfire last year in Southern California that burned 440 square miles (1,140 square kilometers).
