A burned tree with white residue on the west side and black residue on the east side indicates the fire came from the east.

Question

Quizplus · Accepted Answer

The direction of the fire can be determined by the char pattern and not by the color of the residue. The side of the tree facing the oncoming fire typically shows more significant charring due to exposure to higher temperatures, while the opposite side might have less or different patterns of damage. The color of the residue alone does not reliably indicate the fire's direction.
