A Forest Service engine crew member keeps his eyes to the green, watching for spot fires that could ignite from stray embers in the unburned fuel.
After constructing indirect fireline away from the wildfire's edge, a firefighter begins to burn out the interior fuel to secure the fireline and starve the wildfire of its fuel.
I was once told by a seasoned fire manager that the job of a firefighter was 90% boredom, 7% excitement, and 3% sheer terror! Sure, there are some slow days waiting for assignments or mopping up hot spots on a dying fire, but make no mistake about it, the job is not an easy one, physically or mentally, and requires a fearless attitude to be successful.
