Firefighters have increased containment on the Park Fire near Chico, California, which at 621-square-miles as of Friday is now the fourth largest wildfire in history.

The fire, which covers parts of four counties—Butte, Plumas, Shasta and Tehama—has a massive amount of resources assigned to it. More than 6,000 firefighters, 537 engines, 148 water tenders and 41 helicopters are fighting the blaze.

Several evacuation orders and warnings are still in place. Several roads remain closed.

“The primary carrier of this fire are the annual grasses and brush, with mixed timber. Fire in deep drainages, lava rock, and heavy fuels continue to make suppression difficult,” a CalFire update states. “Fixed wing aircraft have been prevented from operating in some drainages due to limited visibility from the thick smoke. Crews continue to build containment lines and conduct structure defense in affected areas.”

The fire is now at 397,629 acres and is 24% contained. It was 18% contained on Wednesday, and it was 12% contained on Tuesday.
