Saw line. The fire has been burning areas of unburned fuel inside the boundary of black. Today we worked on reinforcing the retardant line with a saw line. The goal is to remove heavy fuels with the chain saw. By keeping unburned areas it helps re-growth and controls erosion. Also in this case the fire could still spread up the ridge line to the top of the mountain then back down to the fish area (very small chance of that happening). One more thing, I got another Helicopter ride.
