Thrilled that you took the time to answer, thank you! I learned a lot from you there, glad I asked! Sitting in a kayak beside this tree I could just reach the top of the stump/bottom of the small tree with my hand. You can't see it in the photos, but there is a small hole in the wood where someone has placed some round stones which were painted red... No idea what the significance of that is, just thought it was cool :)
