It could well be a London Plane tree too. Was it harvested near a river or near the suburbs? Either way, basically the same wood.
Nice picture! Is that a Tamarak/Larch? I have never seen a rust orange one. Our tamarak go golden yellow before losing needles. It's hard to tell in the small photo but it looks like a dead pine to me with those colors.
Dawn Redwood. Green 2 seasons. Pumpkin orange in the Fall. Bare in winter. Got about 15 around the property.
