Wind and Trees

Saturday night's high winds were enough to topple this white pine tree in my back yard. Fortunately, the top fell in a driveway, not causing any property damage.

The tree's leader had been destroyed (white pine weevil?) leaving a cup in the crown formed the side branches turning up, where water could stagnate and rot could enter.

The tree sheared along the rot, which shows as black in the remaining wood of the stem. It can also be seen in the adjoining end of the broken top.

A tree's true health shows during the stress of windstorms.
