About 10,000 Arizonans have been forced to flee from their homes as wildfires continue to consume wide swaths of the southwestern United States today. Three dozen fires are raging across parts of Arizona, New Mexico, Colorado and California, as well as Texas and Georgia, forcing additional evacuations and slowing traffic to a crawl as highways in the path of the firestorms are closed. 
 
 Walls of flames have reached 10 feet in some areas, and have burned more than 1.2 million acres. 
 
 "I feared for my husband and my animals [and] for the air quality," June Carter, an Arizona evacuee, told ABC News. 
 
 More than 700 firefighters have come from across the country to battle what has become known as the Monument fire south of the city of Sierra Vista, Ariz., which has been burning since last week. 
 
 The Wallow blaze, in eastern Arizona, has consumed 519,319 acres, as more than 3,500 firefighters attempt to defend against its advance. Despite its size, the fire has only destroyed 32 homes and four rental cabins. Containment rose to 51 percent Sunday. 
 
 Sen. John McCain, R-Ariz., came under verbal fire today for partly blaming the fire on illegal immigrants. 
 
 "There is substantial evidence that some of these fires have been caused by people who have crossed our border illegally," McCain said Saturday at a news conference. "The answer to that part of the problem is to get a secure border." 
 
 A U.S. Forest Service spokesman, speaking of the Wallow fire in Arizona, said there's no evidence it was caused by immigrants. McCain's office said today that he was talking about fires in general, not just the Wallow fire, and that there is evidence smugglers and illegal immigrants have caused fires on the southern U.S. border while camping or traveling. 
 
 The other major fire in the area, in Cochise County, Ariz., called the Horseshoe Two fire, has charred about 210,000 acres and destroyed 23 structures since it started May 8. 
 
 Diminishing winds today should help firefighters battle the blazes, after a week's worth of sustained high winds that helped fuel the fires. 
 
 A recent drought has also led to dry, dusty conditions that help wildfires thrive. 
 
 "What we're seeing is prolonged droughts. We're seeing more fires, more weather extremes," Tom Tidwell, chief of the U.S. Forest Service, said. 
 
 Along with Arizona, Texas has been the hardest hit. North of Houston, a 14,000-acre blaze is among the largest east Texas has ever seen. 
 
 The Lone Star state's worst droughts in recorded history have played a role. 
 
 "We rank behind 1918 and 1956 because they were preceded by other dry years, making the water shortages that much more acute," John Nielsen-Gammon, the Texas state climatologist, said. "The period from March through May was the driest ever, as were the periods from December through May and February through May. The period of October through May was also the driest ever and also the driest eight consecutive months on record." 
 
 The fire has burned 15,000 acres, and temperatures are about 100 degrees. The choking smoke forced a 5-hour shutdown of I-45, the only interstate that connects Houston and Dallas. 
 
 "It's dry out, and the smallest little fire with the wind, just like today, it doesn't take long for it to spread real fast," Lt. Dean Hensley of the Harris County Texas Fire Marshal's office said. 
 
 Fires Burn From California to Georgia 
 
 The Track fire, straddling the border between New Mexico and Colorado, which began last week near the town of Raton, is now 90 percent contained. But a new fire is burning nine miles north of Santa Fe. 
 
 That fire has not threatened any homes, the only consolation for southwesterners enduring the worst year for wildfires in recorded history. 
 
 Further east in Georgia, about 200 firefighters have slowed the expansion of a couple 20,000-acre fires in the southeastern part of that state. Smoke shelters are open in Jacksonville, Fla., today because of the noxious fumes resulting from the fires to its northwest. 
 
 In California, firefighters are battling a fire that began Sunday morning that has already devoured 5,068 acres from a Kern County oil field to a remote area of eastern San Luis Obispo County. Five water-dropping helicopters are supporting 337 firefighters on the ground, but there have been no reported injuries and only one structure has been destroyed.

 Arizona U.S. Senator John McCain did a one-eighty Monday, blaming National Forest Service officials for providing him with information that undocumented immigrants and drug cartel members were partially responsible for the Wallow fire. 
 
 “During our tour of the damaged areas caused by the Wallow Fire on Saturday, we were briefed by senior Forest Service officials, one of whom informed us that some wildfires in Arizona (across our southern border) are regrettably caused by drug smugglers and illegal immigrants,” said McCain. 
 
 The Arizona Republican was joined by Arizona U.S. Senator Jon Kyl and Arizona Rep. Jeff Flake. Mr. McCain, speaking Sunday, blamed undocumented immigrants for causing the Wallow fire, now the state’s largest in history. 
 
 Mr. Kyl and Mr. Gosar had defended Mr. McCain, claiming they had been told some fires in the southern part of the state are started by undocumented immigrants. 
 
 Mr. McCain received criticism after saying there is “substantial evidence that some of these fires have been caused by people who have crossed our border illegally. The answer to that part of the problem is to get a secure border”. 
 
 The U.S. Forest Service has not said publicly that any of the fires in the state were started by illegal immigrants. 
 
 Mr. McCain’s controversial comment followed in the wake of an announcement from Arizona governor Jan Brewer, who said the cause of the Wallow fire remained unknown.

– Six states are ablaze in a searing summer that's breaking records for wildfires. More than 1.2 million acres have already burned and some 10,000 people have been forced to flee their homes as flames devour land in Arizona, New Mexico, California, and Colorado, as well as Georgia and Texas. Some 3,500 firefighters have battled Arizona's Wallow fire that has consumed some 500,000 acres, and 700 smoke-eaters are wrestling the Monument fire near Sierra Vista in the state. "I feared for my husband, my animals and for the air quality," one fleeing Arizonan told ABC News. Also hardest hit is Texas, suffering its worst drought in history, where some 15,000 acres have burned in temperatures topping 100 degrees. Helicopters are currently dumping water on a California blaze raging in an oil field in San Luis Obispo County. Soaring temperatures and super dry conditions will continue to make this summer one of the most dangerous. One issue not a risk factor for fires? Illegal immigrants. Arizona Sen. John McCain came under heat for blaming Mexican drug cartels and illegal immigrants for starting blazes, but now says he was misinformed by National Forest Service officials.
