PRESCOTT, AZ - Crews battling the Doce Fire outside Prescott spent the day sleeping so they're rested to get out on the front lines Friday night.
As the sun goes down they'll start working 12 to 14-hour shifts.
High winds are keeping fire crews busy around the clock, but they are still making slow and steady progress.
Firefighters say they're making progress on the west side of the fire, despite challenges like the wind that keeps kicking up. Crews are keeping an eye on the fire day and night.
It's up to the night shift to pull some long hours and keep watch over the fire.
As the sun sets, the challenges grow. The darkness makes it hard to navigate and it's when bugs and scorpions come out.
Firefighters are used to battling wildfires in the dark. They use head lamps on their helmets and light up the area with their trucks.
But the moon has been so bright the past few nights, some firefighters don't need to use their lights.
"It's tough trying to stay awake and stay motivated out here, but we feel like we're making headway out there at night," said Captain Joshua Johnson.
Crews got some help Friday when a crew that had been working a wildfire in Colorado stopped on its way back to California.
The air tanker dumped some water on the Doce Fire and was going to help out some more before heading home.
Aerial attacks are one of the biggest weapons in the fight against the wildfire.
Air tankers were being used earlier in the week, but most of those have been called off to fight other fires.
Helicopters remain to keep up the fight.
The good news is there have been no injuries and no homes have burned.
On Friday afternoon, officials said the fire was 15 percent contained.
