Seventeen people were missing Saturday as the Carr Fire spread in Northern California.
The fire has already killed two firefighters and destroyed hundreds of buildings.
Only 5% contained, it's also sent tens of thousands of residents fleeing from their homes.
More than 38,000 people in Redding and Shasta County have been ordered to evacuate.
Reuters reports some 3,400 ground firefighters and 17 helicopters are battling the fire.
