Document Summary
A blow up is a sudden increase in fire intensity or rate of spread, where the fire leaps suddenly from te ground up into the canopy of trees. Ponderosa pine forests give clues to past wildfires as there are fire scars embedded in their growth rings, which are charred lines that are left behind every time the tree is birned during a wildfire. As a result of low intensity burns, smaller ponderosas were thinned out, leaving nutrients and space for others to grow big and tall. All fires would be put out, 100% suppression. Thousands of young men flooded the backcountry, they cleared trails, built lookouts and fire roads. Organized crews trained to fight fires together: describe the strategy used by the arrowhead ground-based firefighters to extinguish the.
