Basic concepts of wild land fire latest update with verified solutions origin The origin is the area where the fire started. It is also the point from which the fire spreads, depending on the fuels present and the effects of wind and slope. When the fire is human-caused, you often find the origin next to a trail, road, or highway, but a lightning strike or campfire can result in a very inaccessible point of origin. Protect the area of origin for subsequent investigation of fire cause whenever p...
