What type of pattern can indicate the direction of a fire's origin?

A V-pattern is significant in fire investigation as it is indicative of the fire's origin. This pattern emerges due to the way flames travel and spread in relation to the available fuel and the environmental conditions present. The apex of the V-point typically points toward the origin of the fire, while the arms of the V extend outward, representing the direction the fire traveled as it consumed materials.

Understanding this pattern helps investigators determine the starting point of the fire, which is crucial for analyzing how the fire developed and for identifying potential causes. In many cases, this visual cue can assist in pinpointing where the ignition source was located and ultimately support a thorough investigation into the incident.
