I wonder what kind of journey this tree has had? It’s quite a bit larger than the usual driftwood. A tree uprooted in a storm perhaps, the job of sawing it into manageable logs begun but not finished. Washed into the river and taken out to sea. Most likely this river estuary but perhaps another, we’ll never know but eventually, as most things are, it’s washed back ashore to become driftwood on the beach..
