Flame's lasting wound
A fire scar is a wound on a tree trunk caused by fire damage, visible as a charred or healed-over section of bark.
Foresters and ecologists study fire scars to date past wildfires and understand fire history in a region: The fire scar revealed that flames had swept through this grove in 1887.
