Part of an old tree stump at Rainham Marshes, Essex, that's been buried in mud and has only relatively-recently been uncovered. The info board says it could be about 6000 years old but it looked in pretty good nick to me.
I had to take it from this angle as it was an odd shape and I didn't like the portrait format. V2 is just the base section.
