While camping in the forest I came upon a tree that had been struck by lightning. The tree was about 120 feet tall and the lightning blew a chunk of wood about 2" wide and 1" deep all the way down the trunk to the base, However it spiraled in a counter clockwise direction from top to bottom comming a complete 360 degrees in about 100 feet. Curious I looked for other trees in the 2 weeks that I was there. I found five All spiraled counterclockwise. Anyone have an explanation?
