This is a remarkable picture. It really is reminiscent of the hieroglyphs of historical findings. Your ability to capture and recognize depictions such as this is sharp and a true gift.

There's no telling what the trees have witnessed through time and pass the impressions through their seeds or acorns or how ever they propagate. Maybe trees do bleed history in forms of random glyphs and most humans are blinded to them or just refuse to acknowledge them as anything more than sap or stain.

Thanks for sharing this interesting picture.
