LUNA, N.M. (AP) — A massive wildfire in eastern Arizona is burning more acres than the largest in state history, although some of that area is in New Mexico, where flare-ups that skipped along treetops Tuesday threatened a small mountain town.
The Wallow Fire has burned more than 733 square miles since Memorial Day weekend. Fire spokesman John Helmich said Tuesday morning it's not yet certain whether the acreage that has burned in Arizona makes it larger than the 2002 Rodeo-Chediski fire, which burned 732 square miles, destroyed 491 buildings and cost about $400 million to fight.
The current blaze has burned only 31 homes and some other structures. It has encroached into New Mexico about a mile from the working-class community of Luna, where residents were warned to be prepared to flee.
In the state's opposite corner, near the Colorado border, a wildfire fanned by high winds that has forced hundreds of people from their homes more than doubled in size to more than 9 square miles.
"We're watching trees explode before our eyes. It's horrendous," said Barbara Riley, a schoolteacher and bed-and-breakfast owner in the northeastern New Mexico community of Raton. A 20-mile section of the main north-south highway through New Mexico and Colorado remained closed, causing hundreds of travelers to drive hours out of their way.
Crews worked furiously to protect Luna from the Wallow fire, after a successful weekend of no major fire growth despite gusting winds and dry conditions.
Hundreds of firefighters worked along U.S. Highway 180 between Luna and the state line, hacking down brush, using chain saws to cut trees, and burning fuel in the fire's path.
At Luna Lake in Arizona, just a few miles from town, helicopters collected water and flew west to attack flames sending up thick, gray smoke.
Catron County Undersheriff Ian Fletcher said the roughly 200 Luna residents hadn't yet been ordered to leave, but evacuation plans were in place.
Fire spokesman Sean Johnson said the work crews have done clearing brush and setting their own fires to burn off fuel along the state line has so far spared Luna from the inferno.
"That's what's saved the town," Johnson said. "The line is holding. There's no fire in New Mexico that we haven't set ourselves."
Roughly 7,000 residents of the two Arizona mountain towns of Eagar and Springerville on the fire's northern edge were allowed back home over the weekend. Crews had stopped the blaze's northern advance and were trying to corral its eastern push into New Mexico.
