( All the pics... )
As far as I can tell, this is an entire dead tree that fell over; the base is still in the ground. I'll take a closer look tomorrow to see if it might be alive, and if so, try to right it, but judging by the utter lack of leaves, it probably hasn't been alive in a while.
If it's dead, I'll probably just cut it off at ground level, cut it into chunks, and bring it to the January Beer 'n Burn. :-)
