Fire Dozers
bear,
Thanks for the interest... Almost always cast away from the direction the fire is burning. This leaves a bare (different word, but close to pun) edge if and when the fire hits it. If you cast in, you leave a big berm of dirt with grass, weeds, sage brush, etc., mixed in. If that fuel gets on fire...when the
fire bumps it... it can stay hot for days... makes for a real mop up hassle. I
have, on rare occasions, dozed the berm right on the fire to put it out, and
that does work... You absolutely need the say so from your dozer boss before
doing it... and it's rather unpleasant, even in a AC'd cab.
Line width is usually dictated by fire managment... however, I've seen miles
of fire; little wind, short flame lengths, pretty flat, stopped by a simple cow path/trail. In timber... well, if it's in the tops... "crown fire", and windy... the
fire can be spotting a half mile, a mile, even farther, in front of the main fire.
If all those 11's that were pushing together in that posted picture, had made a cat line like that before the fire, there would have been a good road and
parking area for engines after the fire went through. You just can't stop them that way.
Thanks bear...OCR
