|Clump of mushrooms growing out of a driftwood log.|
Maybe four links: people felled the tree, possibly. Then the ocean carried it to Salmon Point and threw it onto the shore. Here, mushrooms are eating the wood. And something is enthusiastically eating the mushrooms; the bites look like those of slugs or snails.
I looked for the slugs, but they are usually night feeders, especially out in the open. I couldn't see any, nor any sleeping snails. The logs make good, sturdy roofs for slug bedrooms, down in the dark and damp.
