SPRINGERVILLE, Ariz. (AP) - For the first time in more than a week, crews made some headway in the fight against a major wildfire in Arizona's eastern mountains that destroyed dozens of buildings and kept thousands of evacuees away from their homes.
Officials said the 603-square-mile blaze was 5 percent contained, after helicopters and a large air tanker dropped fire retardant and ground crews lit blazes to burn up combustible materials nearby. They said among the buildings destroyed so far were 22 homes in the resort community of Greer, and five others were damaged.
Fire information officer Jim Whittington said unfortunately, losing homes to wildfires has become too common.
"If you've been with those folks when they go back in, it doesn't matter if they're rich or poor, if they live in a mansion or if they live in a very small house, the pain on people's faces is exactly the same," he said late Thursday. "Our hearts go out to those folks."< /P>
Authorities said the 386,000-acre fire was sparked by a campfire. It is the second-largest wildfire in state history.
Smoke from the burn operations puffed shades of black and gray in the hills above the town of Eagar as grass singed and trees lit up orange. Crews were trying to keep the flames from hooking around and making a run for Eagar and nearby Springerville.
It wasn't clear when residents would be allowed to return to Greer and the handful of other communities in the mountain forest areas of eastern Arizona. Their return would depend on weather, fire activity and the bolstering of miles of fire line.
Thursday was the first day that firefighters had favorable weather conditions and mild winds also were forecast Friday, before the return of gustier breezes Saturday.
"(Friday) is a window to get stuff done so we're going to be hitting it pretty hard today," fire information officer Suzanne Flory said Friday.
Crews remained in the Greer area, where the fire was active, and built containment lines across the border in western New Mexico. The flames had yet to reach that state, but residents of the town of Luna were preparing to evacuate.
New Mexico Gov. Susana Martinez was scheduled to visit the area Friday to discuss fire preparations. A day ago, Arizona Gov. Jan Brewer flew over burned areas in her state and met with evacuated residents in Lakewide.
"They're very resilient people up there," she said Thursday.
The fire has rekindling the blame game surrounding ponderosa pine forests that have become dangerously overgrown after a century of fire suppression.
Some critics put the responsibility on environmentalists for lawsuits that have cut back on logging. Others blame overzealous firefighters for altering the natural cycle of lightning-sparked fires that once cleared the forest floor.
Either way, forests across the West that once had 50 trees per acre now have hundreds, someti mes thousands, and much of the landscape is choked with tinder-dry brush.
The density of the growth has fueled immense conflagrations in recent years, like now burning in the Apache-Sitgreaves National Forest.
"I think what is happening proves the debate," said state Sen. Sylvia Allen, a Republican from rural Snowflake.
In the past, a 30-square-mile fire was considered huge. "And it used to be the loggers got right on it. Never in the past have you had these huge fires."
Today, it's not uncommon for fires to exceed 150 square miles.
An extremely dry late winter and spring contributed to the fire conditions, drying out the forest and allowing fierce winds to carry the flames into the treetops, where they spread by miles each day.
Many in Arizona blame the legal battles that have erupted over old-growth logging that threatened endangered species such as the Mexican spotted owl. Since those disputes prevented regular logging that would have th inned the number of trees, the forests became overgrown, they say.
Environmentalists insist that theory is just a scare tactic.
"That's just wrong, flat-out wrong," said Bryan Bird of WildEarth Guardians, which has been involved in some of the lawsuits. "These people are misinformed or they're intentionally trying to scare people in a time that they're already terrified. It's pure politics."
Experts such as professor Wally Covington of Northern Arizona University, who has studied Western forests for decades, say the problems have been building for decades, and blaming lawsuits ignores those facts. Nearly half a million square miles of ponderosa and conifer forests are at risk across the West, he said.
Historically, those forests were relatively thin, with grass and wildflowers growing beneath the canopy. Every two to 10 years, a fire would move through and burn out the undergrowth and small trees.
As the region was settled in the 1880s, cattle we re brought in to feast on the grass, which limited fires and let small trees mature. Early foresters liked that, because they wanted the forest fully stocked with trees. And they began putting out fires early in the 1900s to help the trees grow, Covington said.
As the forest got thicker, fires got harder to fight, and the U.S. Forest Service hired thousands of men to battle the flames. Small fires that reached into the treetops were first seen in Arizona in the 1940s. Over the following decades, the typical treetop fire went from a few acres to a few thousand to more than 10,000 by the 1990s.
Then early in the 2000s, huge conflagrations emerged that turned hundreds of thousands of acres to ash.
"Now, we're firmly in the multiple 100,000-acre landscape fire,' Covington said.
Sen. Jon Kyl, an Arizona Republican, says environmental lawsuits have put the nation's forests at risk. And in places where the Apache-Sitgreaves forest had been thinned, he said, c rews were better able to control the fire.
"So it does work," said Kyl, who has a cabin in Greer. "And we haven't been able to do as much of it as we would like."
The Forest Service has acknowledged the problem, setting up nine restoration projects across the West designed to let private industry thin small trees. In Arizona, the Four Forests Initiative is expected to help clear about 50 square miles a year and use the discarded brush for construction material. But the plan isn't off the ground yet, angering some, including Allen.
When the plan does start, it will build on projects already under way in the state's White Mountains, where similar efforts are credited with saving some communities from the current fire.
