SPRINGERVILLE, Ariz. -- Crews are finally making some progress against the massive wildfire that's been burning in the mountains of eastern Arizona for more than a week.

Fire officials say the 600-square-mile blaze is 5 percent contained. Helicopters and a large tanker have been dropping fire retardant, while ground crews have lighting back fires to burn up other materials that could allow the blaze to spread.

Officials say they now have a brief window to try to expand containment. Forecasts call for winds to remain relatively calm today, with gustier conditions expected to kick up tomorrow.

The fire ranks as the second-largest in Arizona's history. It's destroyed dozens of buildings, including 22 homes in the resort community of Greer. Crews are trying to keep the flames from spreading to the towns of Eagar and Springerville. Thousands of people have been evacuated.

Authorities say the blaze was sparked by a campfire.
