Ruidoso, New Mexico (CNN) -- For 15 years Kari Greer has been documenting wildland fires and the men and woman who battle them.
"I'm a trained firefighter; photography is my tool," she says. "It's my service on the line."
In college Greer studied photography but spent her summers fighting wildland fires as a seasonal firefighter. After graduation it was an easy fit to combine her two skill sets.
She now photographs fires from the front lines under contract with the National Interagency Fire Center, the federal outfit that supports wildland firefighting efforts.
Her photos are available to the public and the news media and are used to train firefighters and to help better coordinate firefighting efforts...Read here, photos...
"My whole focus is to show the activity -- what's going on," says Greer. "I feel the heat, I feel the smoke."
