That's an "Aspen" tree for sure, nice job on the big beast.
You could have dropped that and put a swingmill over it and turned it into lumber providing there was no metal in it.
Great pics Mark, and a well managed job all round. Don't you just love the little riders all along the minor branches, we get those on seriously declining Eucs here too a dead give away that something major is happening in the tree system for sure.
