Started on May 29, the Wallow Fire, located near the Arizona and New Mexico border, had already burned 389,000 acres when Landsat captured a stunning aerial image of it on June 7.

Smoke from the fire has affected air quality as far north as Wyoming and as far east as Georgia. The U.S. Geological Survey and NASA cooperate closely in managing the Landsat program and we have them to thank for images such as this.

Thanks for the klm file and the update. It is great to share information about this monster fire
I think you have hit the nail with your definition Bill. Another way to look at it is this; burning out is part of line construction and the decision to carry it out is made at the resource boss level(engine, crew). Back firing is a larger scale operation, and responsibility for making the decision to engage lies with the OPS section Chief, or branch director.
Thanks to the brave men and w0man from around the country,for such a great job you are all doing to protect life and property. And keep the poeple of the area in your prayers. the USA is such a great country.
