In reply to franhammond92:
There was half a dead tree on the path on Sunday morning, just left of A Millers Tale. (So possibly a different tree to the one mentioned in the original post?!). Looked like it had come down quite recently, possibly the night before. I tidied it up and moved to the side.
From what I could see above, it looked like it had snapped part way up the trunk so there is still some lurking up there.
