A huge wildfire in the American state of Arizona is now in its 11th day - and it's still getting bigger. The blaze has forced thousands from their homes.
The fire is being called the Wallow fire, named after the Bear Wallow Wilderness area where it's raging.
This photo, taken by satellite by space agency Nasa, shows how the wildfire has spread. There are fears that the blaze could cut off electricity to hundreds of thousands of people.
There about about 2,500 firefighters battling the blaze - drafted in from as far away as New York. Here they're taking a break.
The firefighters' work isn't being helped by strong winds which have been moving the flames five to eight miles per day.
So far no-one has been hurt. Here a helicopter drops water over the fire. It's thought the blaze could have been started by an unattended campfire that was let to spread.
Here a man hoses his house down in the hope it will stop the flames taking hold.
Thousands of people have had to evacuate the area - and more are being warned to get ready to leave their homes.
