Tree Lightning Damage: Spiral scar
This smaller tree in Spring Hill Cemetery, Charleston, WV was struck by lightning in July of 1998. The scars on this tree are narrower towards the
bottom of the trunk, and wider towards the top. Notice the spiral pattern
the scars seem to follow down the trunk. Some speculation has attrubuted
this spiral path to the lightning's magnetic field, but it is actually
caused by the tree's spiral internal structure.
