The patterns on this bark look amazing. Not just the underlying pattern of the tree, but the strange markings on the bark itself. I don’t know what made this odd saw-tooth pattern, and I’d be tempted to say it wasn’t made naturally, but, hey, who knows?
Our brains are wired to spot patterns. We look for the connections between things, and we constantly try to match what we see to what we’ve already seen. There’s something wonderful about spotting the unusual, about noticing difference.

This pattern is caused by a lichen and a fungus that are symbionts, as far as I know. I have seen it before and often on birch tress. What concerns me more is that bark appears loose and this could kill the tree. A dose of Slicea 6x, 20 drops on a litre, 50 succussions and mixed with 19 litres of water may save it.
