Hard for me to know without the leaves. If it's maple or some good wood for turning I'm going after another load while I wait on a lathe. Some of it seems to have a curly grain.
The most accurate way to identify wood is to study the end grain with a magnifying glass and Bruce Hoadley's book, "Identifying Wood".
The sap and heart woods remind me of silver maple — especially the blond chatoyance of the sapwood. Silver usually has a furrowed shaggyish kind of bark and it’s hard to tell from the pics the bark details.
Certainly consistent with maple.
