I really enjoy looking at tree bark - the whorls and swirls of bark as it moves up the trunk of the tree. It overlaps like house shingles. And it eddies around limbs and around the stumps of fallen limbs. You see the tree holes, and the flow of the bark around them.
The patterns are mesmerizing, like watching water that is stopped.
It really seems like something is written on the tree, by the tree, over and over again.
And when a vine climbs the tree, it is even more beautiful, especially in the autumn when the vine turns red.
