After a
great overnight storm, i drove the parkway the next
day and stopped around Mills River Overlook on a
whim and noticed this great Spanish Oak on the
margin of the wood that had been struck by
lightning.
Lightning
strikes at some 250,000 amps and uses whatever it
hits as a conductor to the ground. That's what it
had done to this tree and it had split the tree's
bark from tip to ground in a rough spiral down the
tree.
Lightning
is one of the natural fire-starters for forests,
but i guess it had been too moist and too early in
the season and not dry enough to ignite
anything.
I can only
imagine that the tree was in shock. The pattern of
chlorophyll in its leaves were reduced down to near
the main feeders (see below) and the rest of the
leaves were already brittle and dead tissue.
The area of
influence around the ground was about a 15 foot
radius from the trees base. Some smaller trees had
1/2 dead leaves on one side and the other part of
the tree, farther away from the struck tree, was
fine. Just an odd pattern.
