Document Summary
Create its own weather by the intense heat driving invisible chimney of heat miles into atmosphere. Through fire scars, every time it is burned you can see the growth rings embedded in them. Fire created opened grown forests with big trees. Lots of space b/w trees b/c only some survived during the past fires. Little rain fell and rockies were tinder dry. Cold front moved through and picked up wind speed which erupted the speed of the fires. Caused small fires to merge into huge fires: describe the strategy used by the arrowhead ground-based firefighters to extinguish the clear. Create fire line or fire break (make it 1. 5 times the fire is high and you deny fuel to the fire. Take out trees first because they are the largest fuels. Cut, chop, dig to scrape down to bear minimal soil so that the pine needles etc don"t ignite and grow the fire.
