We are still wandering about in the wilds of Connecticut in an empty flood control reservoir. When they built it, they cleared out a village and, along with the village, some very, very big trees.  This was an elm, growing as elms like to do, right above the river in the flood plain.  The man is a bit over six feet tall. The tree is an easy four plus feet in diameter when measured across the top of the cut. It must have been a magnificent tree, and a lovely river bank, for both sides of the stream were lined with these elms, all the way down through the old village.
