After an impressive electrical storm hit the Lakes Region back on
July 17th I took a look around for signs of strikes but didn't find anything. Then this week, while doing trail work in the
Hamlin Conservation Area, someone with a good eye noticed two trees with the sure marks of lightning.
I can't tell if these date from the July storm, but given their prominent location, I would guess they are from a more recent storm. When struck, current takes a path down a tree just under the bark where there is the most moisture, providing the best electrical circuit - current always takes the path of least resistance. The rapid heating due to the high current expands the moisture in the sap, instantly vaporizing the water, which blows the bark right off the tree.

The resulting long strip of exposed wood may or may not kill the tree; these strips, though long, are narrow so the tree may survive. Lightning is fickle - these two trees are about 50 yards apart, and neither are the tallest in the area - why these particular trees?
They are easy to find if you want to see them for yourself. They are just 0.1 miles from the trailhead kiosk, one right beside the trail on the right and the other just down the slope on the same side of the trail. While you're in the area, walk down to the first trail intersection and see the freshly trimmed field there.

You might come across some wild blackberries which are ripening now - look along the edges of sunny trails and wood roads.
Also be sure to keep an eye out on your travels for the late fall flowers that are blooming now.

Some of which have visitors.
