The squarish cut-out place in the bark where wood shows through looks man-made. That’s what drew me to this tree at first, although based on its location on our property, that seems unlikely. Then I became fascinated by the shiny brown substance that has filled in other wounds. It is hard to the touch, almost like dry paint. It probably isn’t a true mystery, only that I do not know how it came to be the way it is. It evokes calligraphy.
