Most firefighters have a favorite environment in which to fight fire. Mine is ponderosa pine forest, like this one in New Mexico’s Gila Wilderness. It looks hellish, but the lack of brush in the understory means the fire is easy to contain. As the ponderosas heat up, they give off a smell like butterscotch and the light of the fire magnifies the orange in the bark. If I could, I’d fight fire entirely at night.
